I voted for GT7, because that's the one I'm most curious about of all the ones that'll probably be there. Not quite sure why tbh, because I'm sure God of War will be much more impressive and is even more likely to show up, but it is what it is.
My absolute biggest wish would be a new Uncharted game to be announced, looking suitably next gen. We know Bend were working on it at some point, and I just can't believe Sony would abandon an IP as big as that, so surely SOMEONE is working on it, right?
