Well, I'm not sure why that would mean they couldn't allow a 'Turn Off' option. After all, according to Weaste this was there originally. You'd just turn it back on for VR - much easier than buying a PS Eye, which they haven't included now as they intended.
They listed a ton of devs who are 'on board' with it; Unity, Ryse, Crytek etc. Obviously, first party will be - I imagine Naughty Dog, and one of the slides they used earlier used a model taken from that Shadow of the Colossus game.
Gonna be interesting. It's 1080p with 360 degree tracking and 90+ field of view. Surely it's going to be expensive, but they've also mentioned how 'one of the advantages of consumer products is price' and if they want it to do well.... how much do we reckon?
Similar price to the PS4? Less? More?
