News is coming out that the PS3 killer app Killzone 2 is set to be shown at E3.

The game is going to be shown to the gaming world during an invite-only pre E3 event.

The event is expected to have about 150 invited guests attending to see the game in action. The expectation at this point is that Killzone 2 is going to be shown in a playable form.

What this form is going to be is not yet known because it is not known whether it will be a single-player demo, multiplayer, etc.

Also it is not known what the game will look like as it has not yet been shown in any form since E3 2005 when the game was unveiled in a video-form showcasing amazing photo-realistic visuals which many stated could not actually be achieved in playable gameplay.

Sony has the invite-only event going against the Microsoft keynote event as well in an attempt to steal thunder from the Xbox 360 and Microsoft. It seems that Killzone 2 will be ready to try and steal the show at E3 2007.

So, you may have heard the news about Manhunt 2. Getting a complete ban, subject to appeal, by the BBFC in the UK, followed swiftly by a AO rating from the ESRB in America - which effectively places great restrictions on where the game can retail although the ESRB is a voluntary system.

Recently contacted by gaming bloggers at Kotaku, both Nintendo of America and Sony Computer Entertainment of America have now confirmed that they will not be allowing titles with an Adults Only rating onto their respective platforms, the Wii and PlayStation 2 and PSP.

With no PC version of the game currently planned, the game is essentially homeless and Rockstar is left with the options of either abandoning the game completely, re-developing it with a less violent theme, or hope to God that an ESRB appeal will lead to a different outcome (not likely).
