A lot of cool ideas here. I especially like bringing it back to the crazy, bring back the in game rewards, bring back the customizations, having a female protagonist (someone like Catlina who is completely psycho; a redhead...by default at least), a huge map, and a huge amount of side missions.
Basically a new San Andreas.
However, I was wrong in my prediction: no GTA was announced at E3.
Sorry. I assure you that there is a GTA on the way.
I think the lack of announcement may be a good thing: it indicates that a certain platform developer didn't try to snag some sort of exclusivity.
Hopefully this means that it will be equal across all platforms and the PC version will be playable out of the box.
