Most of the nausea issues in VR stem from the disconnect between moving in virtual space without moving in the real world, and Apple seems to be focusing on applications which maintain a 1:1 mapping between real and virtual movement. Games are where that's most likely to be an issue and they're very much not focusing on actual VR gaming, only playing non-VR games in VR on a virtual screen.
