I'm not going to watch any footage of uncharted 3's campaign, I don't want to spoil it. GTTV will only show co-op though, it will be the first time we'll see it. Thursday will be fun.
I want to see more of these though because info is still scarce:
The Last Guardian
Mass Effect 3
FF Versus XIII
I'm also curious to see how Peace Walker and the PSP GoW games look on PS3.
A glimpse at Persona 5, no matter how small, would make my year.
The wait for half-life 3 is driving me crazy, I can't believe Valve wont even be at the show.
