If the VR system has a 2 tier approach both compatible with battery mode and docked mode performance with an attached usb power cable. I think we are looking at wii level or just above for portable VR and about wii u/360/ps3 docked allowing for the fact it will need minimum locked 60fps or beyond 70/72/75hz depending on the refresh rate of the screen.
So I'm thinking of a possible VR pack in title as a combined version of both Mario Galaxy 1 and 2. That would be the comfortable level for Switch VR even on battery. Another possibility is Zelda windwaker because it has very beautiful graphics and would be again easy to run on the hardware even in portable mode. I'd be happy with a high res VR version of mario 64 to be honest though. Nintendo have the content to deliver on VR.
