YOU ************ NO UNCHARTED 4 WHAT THE FUCK
Oh just read your post, okay.
This is very hard since you dont know what the new IPs are. But I am going to take a safe bet and choose a game I actually know (somewhat) how itll play.
It's between Killzone 4 and Gran Turismo 6. See, I love Killzone and I think it'd be best to build it up with a console launch. So yeah my vote goes to Killzone 4.
With that said: I think Sony might benefit the most from launching Gran Turismo 6.
So in short: Both.
