As someone who has never owned a Playstation before this, some sort of Resistance, Uncharted, Killzone and God of War collection would be great! Though I suspect that 3 of those 4 franchises will be brought out to the back and shot, so it's probably not going to happen.
I fully expect an Uncharted 1,2,3 + Golden Abyss collection in the Summer of 2015.
I look at something like Destiny: An entire co-op centric game but if you want to do it alone, go right ahead. That's where I see video games going. And I think its not a bad place to be.
Of course, I want my Uncharteds and my Mass Effects. And those will always have its place. But the future seems like it might be headed to single player with seamless co-op (if you desire) and that seems fine)
