I've seen rumors that the PS4 and Xbox One can support 4k resolution and 3D output, but I haven't seen any games pull the trick yet.
I've been considering having a 20' wall painted to support a 3d projector, but I don't yet see the point beyond a few movies.
I doubt any games will support -both-, but I'd like to know if Destiny (with it's 'immense' landscapes and immersion) plans on supporting either.

They cannot support play 4K games, and the whole 3D craze is morphing into the VR Headset thing now.
