Yeah Nintendo 3DS XL was awesome, but even then, you'd have to use that one specific console in order to be able to play that game.

What we're thinking is to enable this technology - as long as there is a camera and a screen - instantly accessible across billions of devices.

That means that the 3D effect would be applicable not only for games built for that specific console - but for any and all games that are already in a 3D environment.
