As every big release these days has platform partnership of some sort, we can infer that:
AC will return as a PS partner.
Cod Black ops 3!
Not sure about EA, but NFS, mirrors edge and battlefront could all be PS.
Dishonored 2 might not have one yet, no release date yet.
Mad Max?
Xbox 3rd party partnership summary:
Rainbow 6 siege
The Division
PvZ GW2
Dark Souls 3
And of course Tomb Raider...
...And Fallout 4! Thanks for reminding me
Enjoy E3
