There are many games on the PS3 lining up to support either PlayStation Move or 3D. Or both! Valve's Portal 2, however, is not one of them. For that, you'll have to wait until Portal 3.
"[Move and 3D] will have to wait for Portal 3 or another title," Valve's Doug Lombardi tells PSM3 magazine. "We won't be supporting those in Portal 2."
Just thinking about Portal 3 in 3D with motion support is enough to make me sick. The first Portal made me queasy enough. Then again, just because Lombardi says "Portal 3" doesn't mean there will be a Portal 3. There was supposed to be a Half-Life 2: Episode 3 too, and look what happened to that!
