(EDIT: doesn't The Vanishing of Ethan Carter get it's ps4 release this year? I think that was a definite 2015 ps4 release. And the PC version released months ago.)
It's not a great list, but even just one AAA release would've made a massive difference.
The thing is, there is actually a lot on this list I'm excited for.
Really excited: everybody's gone to the rapture, Rime, journey ps4 (never played my ps3 version, now just waiting for ps4 version)
Excited: Alienation, No mans sky, Until Dawn (fingers crossed, but will wait for reviews)
That's 6 games in just the latter 6mos of the year that I plan to buy that are ps4 exclusive. I feel like that's pretty good, even if I was borderline devastated when U4 got delayed.
