Microsoft sent out invites to the press for a big event it's holding on the 30th of September, 2014. The invite's catchphrase reads "join us to hear about what's next for Windows and the enterprise." Speculation is rife about what Microsoft plans to launch on that day. The most plausible theory talks about a possible Windows 2014 launch, the next addition to its enterprise operating system family. A less plausible theory speaks of Windows 9, which is really a client operating system. Microsoft wouldn't specifically mention "enterprise." Windows 2014 could be loaded with features for the next-generation of enterprise environments, which are increasingly leveraging the cloud. It wouldn't surprise us if Microsoft took a big leap in favor of the new breed of ARM + x86 hybrid CPUs, and high-density ARM-based servers.
