Microsoft Windows 10 will launch on the 29th of July, 2015. This is when existing users of Windows 7 and Windows 8.1 will be able to upgrade to their applicable variant of Windows 10 for free; PC makers ship desktops and notebooks with the OS pre-installed; and when you will be able to buy Windows 10 copies off the shelf.

Microsoft is expecting at least 350 million users of Windows 7 and Windows 8.1 to freely upgrade to Windows 10 by the end of the year, many of which could upgrade on day-one, clogging Microsoft Update. To mitigate that, Microsoft launched a "reservation" system. Current users of Windows 7 and Windows 8.1, woke up to a curious Windows logo in their system-tray, which launches a tiny app that lets you "reserve" your upgrade (a position in the queue to upgrade). When your time comes, Windows will fetch the Windows 10 upgrade image from Microsoft Update. The actual upgrade process will be similar to that of Windows 7 to Windows 8. You can choose a clean install, or upgrade over an existing installation. Once installed, your Windows 10 license is tied to the machine forever.

MSI posted a reveal trailer (yeah, we have those for graphics cards now) for its flagship GeForce GTX 780 Lightning graphics card. In addition to the highest factory-overclock among MSI's ranks (currently held by the GTX 780 Gaming Series), the card reportedly features redundant BIOS, and a feature that lifts various BIOS-level limits, protections, or fail-safes. If we understand this correctly, the GTX 780 Lightning should be among the first GK110-based graphics cards to feature over-voltage beyond NVIDIA's limits. Very little is known about the card's design, but given that MSI's new TwinFrozr IV cooling solution leaves GTX 780 Gaming Series with overclocking headroom, and runs cool enough, it wouldn't surprise us if MSI sticks to that cooler, albeit paint it yellow. As for the release date, MSI plans to launch the card on the 7th of August, 2013.The reveal trailer follows.

A presentation slide, allegedly by AMD, leaked by a Japanese distributor confirmed specifications of AMD's upcoming Radeon HD 7790 graphics card. According to the slide, the HD 7790 is indeed based on a brand new silicon, with a transistor count of 2.08 billion. Compare that, to the 1.5 billion TC of "Cape Verde," and 2.80 billion of "Pitcairn." The silicon is built on the 28 nanometer silicon fab process.

The clock speed mentioned in the slide could be core, which is clocked at 1.00 GHz. Next up is the stream processor count, which stands at 896. The HD 7790 is mentioned to feature a primitive rate of 2 prim/clk, suggesting that its component hierarchy is more similar to "Tahiti" than "Cape Verde," which could mean double the tessellation processing power. All said and done, the HD 7790 belts out 1.79 TFLOPs of floating-point performance. The source goes on to mention in its text that the card features a 128-bit wide memory interface, memory clock speed of 6.00 GHz (96 GB/s), a TDP of 85W, and a single 6-pin PCIe power connector. It is expected to launch no later than tomorrow (22/03).

Those who marked Spring of 2013 as the most beautiful time of the year to come -- because your favorite game franchise has one coming for you -- will have to spend almost the entire season watching blooms and leaves sprout. Amazon revealed the definitive launch date of GTA V to be June 19, which is just two days short of June 21, the official start date for Summer. The addition to the hit game franchise will arrive on Xbox 360 and PlayStation 3 first, even as Rockstar "considers" other platforms, such as you know -- TFLOP/s capable PCs.

Pre-order cards of Call of Duty: Black Ops II being sold by retail chain Target ended up revealing its release date to be 13th November, 2012. Developed by Treyarch for Activision, Black Ops II is the 9th game in the Call of Duty franchise, and a sequel to the 2010 title Call of Duty: Black Ops, which is among the most commercially-successful video games in history. A reveal trailer of the game is expected to be posted tomorrow.

The bets are off, there indeed is a new installment to the Halo franchise in the works, called Halo 4. Its release date was announced to be "Holiday 2012", more specifically 6 November, 2012. Microsoft and 343 Industries confirmed this date on Tuesday. "Set in the aftermath of Halo 3, Master Chief returns to confront his own destiny and face an ancient evil that threatens the fate of the entire universe. Halo 4 marks the start of a new trilogy that begins with its release in 2012," an Overview page on Halo website reads.A video presentation follows.

It 'tis the season of rumors and assumptions for this years winter time blockbusters. According to Computer and Video Games, the following information, claiming to reveal the game's release date and a load of multiplayer features, was first posted on the official Black Ops forums in a thread that was later taken down, and its cached version is unavailable. It was then reposted in another thread on Activision's forums, which was also killed off by the publisher, but its cache remains available (via MP1st). None of this information is confirmed, but there's no reason it couldn't be genuine as it all sounds feasible. The list is full of new modes but makes no mention of a new game engine.

A slip-up by online marketplace Amazon.com saw the release-date of Blizzard's hotly anticipated hack-and-slash RPG title, Diablo III getting leaked. That date is April 17, 2012. The date has since been removed from Amazon. What makes this slip-up a credible leak and not an error, is the fact that Blizzard has been talking about a Q2, 2012 launch for the game.

We finally have a concrete release date for BioShock Infinite. Irrational Games has announced that BioShock Infinite will be released on October 16, 2012.

""ioShock Infinite has been our sole focus for the last four years, and we can't wait for fans to get their hands on it."

BioShock Infinite will be available on the Xbox 360, PlayStation 3, and Windows PC with an international release of October 19, 2012.

The launch of Futuremark's anticipated DirectX 11 graphics benchmark suite 3DMark 11, has been delayed. The software was earlier slated for release on the 30th of November, with pre-ordering already underway. The company is citing last-minute bugs as a reason for the delay. In a circular to the press, Futuremark said: "Over the weekend we made the difficult decision to postpone the launch of 3DMark 11 by a few days. Our aim is that 3DMark 11 should provide accurate, reliable and consistent results from the start. With that goal in mind we are taking some extra time now to fix a couple of difficult bugs rather than patching the benchmark immediately after launch."

The company does not have a new release date at hand, as it doesn't know how long the last-minute bug-squashing will take. "It might take a day, it might be a week, but either way we'll be in touch again soon to confirm the new launch date...," the circular added. 3DMark 11 is a comprehensive 3D hardware performance benchmark suite that makes use of the DirectX 11 API, making use of the very latest in consumer 3D graphics. It also provides an insight into what level of detail and realism one can expect from this generation of graphics processors.

Today during a keynote address at Computex 2009 in Taipei, Microsoft's OEM Division Corporate Vice President Steve Guggenheimer revealed that the company is confident with the progress made with Windows 7 and Windows Server 2008 R2, and that as a result, Microsoft will deliver Release to Manufacturing (RTM) code to partners in the second half of July. Windows 7 will become generally available on Oct. 22, 2009, and Windows Server 2008 R2 will be broadly available at the same time.

"As we've said many times, quality is our primary goal," Guggenheimer said. "We announce each milestone once we're confident of where we are in the development cycle and that it is ready to be shared with customers and partners. We've received great feedback from our partners who are looking forward to offering Windows 7 to their customers in time for the holidays."
