Waht I don't understand, why has Sony not made a VR team with around 20 devs who are porting PS3 games to PSVR ?
Like Resistance, Motorstorm, Killzone etc...
Gearbox did that with Borderlands 2 and the VR port was done only by a few devs.
Borderlands 2 was already ported to PS4, and then it was ported to VR. The games you mentioned haven't been ported for PS4 so they would have to do that first. Probably don't want to invest that much on those games.
I guess they could port KZ Shadowfall to VR.
