PlayStation VR for sure, and if they play their cards right they might even lead the VR playing ground for some time. They are going to have +/- 35 million PS4 sold by the time PSVR lands. I think that they are going to undercut the PC versions of VR and they are going to be the only real place to experience affordable VR on consoles for a while.
How big VR is going to be in the end is anybody's guess...
