Vita was supposed to be the focus of Sony's presentation. Even in the OT people were crazy about this. Most sites were saying this. We all thought all those PS3 pre-e3 announcements (god of war, ALBR) were because there would be lots of announcements for Vita!]
And it gets... 5 minutes. Most about a game that's on PS3 too. Yeah... Vita had simply the worst e3 I've ever seen for a system. A logo. A port. And a game that frankly was not impressive at all - look at ASS III to see the difference in scope, quality and dedication. Definition of bland spin-off... or at least 30 seconds (30 seconds!!!) told me!
What is said in the "official topic" or speculated on by the internet is not a legally binding contract for companies to dhere to...just so you know.
