Here's a list of exclusive games (for 2015) out or coming out so far.
Bloodborne
Disgaea 5
Everybody's Gone To The Rapture
Fat Princess Adventures
Hot Shots Golf (we'll probably get a date at E3)
The Order
Until Dawn
Onechanbara Z2: Chaos
Omega Quintet
Rime
Tearaway Unfolded
The Tomorrow Children
VizionEck
Wattam
WiLD
I'm missing some remasters and such, but that's what's slated for this year at the moment. E3 could pull up some release dates, like Shadow of the Beast (since gameplay was recently seen a month ago). The game I can see being delayed the most is WiLD due to the lack of info.
Shit might change, and the 3rd party stuff drawfs that list, but it's not as empty as one might suspect.
(Unless your tastes don't fit those games, then I don't know what to tell you!)
