Doug Lombardi, in an interview with CVG, said this relating to PS Move or 3D support for Portal 2:
“[Move and 3D] will have to wait for Portal 3 or another title,” he added. “We won’t be supporting those in Portal 2.”
Interesting. We’re just hoping the PC versions will feature some sort of 3D support, perhaps through NVIDIA’s 3D Vision. As for Move, I think we’d all prefer that any motion support remains either to third-party developers (i.e. Sixense and Novint Falcon), or to homebrew developers (i.e. the numerous Wiimote for HL2 projects).
As for the possibility of L4D ever going to Sony’s console:
“Who knows what the future will bring?”
Oh Doug, you’re such a tease.
