The safe bet would probably be not to expect good launch exclusives. Other than Knack and killzone, what did ps4 launch with that wasn't on any other platform?
I thought Shadowfall was a great graphical showcase but a very average game. I didn't like it at all.
I had a good time with Resogun and still haven't played Knack.
Launch titles are nearly always weak.
But to try and launch with no exclusives is an interesting strategy. It's going to be difficult to generate that "must have" feeling if everything is available elsewhere.
