A playable demo at E3? I highly doubt it correct me if I'm wrong but I don't seem to remember ANY GTA game having a playable demo but I could be wrong there, a Rockstar employee showing us a few stuff on a big screen to show off the game? Possible. Either way allot of the "leaks" seem plausible to me, if it's fake then there is some good ideas in there that would make a really good GTA game, especially the "Radio warnings on a four star wanted level" and "Live traffic reports" it's the little realism things like that, that really make GTA for me =) at least you didn't claim it to definitely be true like some posters have done in the past =)
