Any by then, all the 3rd Party Xbox "exclusives" will have their GOTY iterations on the PS4.2016 is only two years away, is this supposed to be a slight?
Whatever Naughty Dog comes with will be better than anything MS studios comes with, Sony first party stuff is by far better than MSI'd wait until 2017 for their work, I know it's going to be classic.
It's really not hard to see how this will play out in the games department
