Ahh, I looked before you edited! That Neogaf thread has been closed, but it's not 100% debunked. It seems like it originated on a Chinese forum on a newly created account. Some claim it's the same person who apparently leaked sketches of the PS4 pro. I wanna hear more from Neal!
Anyway, it wasn't too crazy, aside from the addition of an additional computational unit that was claimed to also be portable. Otherwise the same Gamepad with detachable controllers and a TV dock that has been widely rumored/mocked up.
