Valve's Chet Faliszek has seemingly confirmed that Portal 2 will feature "full support" for PlayStation Move, although "the system is not yet fully integrated".

Speaking on the German PlayStation Blog (via Google translation), Faliszek said he hoped PS3 console exclusive features like Steam cloud support and Move compatibility would help make up for Left 4 Dead's no show on Sony's console.
He also confirmed that 3D support for Portal 2 isn't on the cards.
Valve boss Gabe Newell said at E3 last June that the PS3 edition of Portal 2 would be the "best version on any console" thanks to Steamworks support.
Seeing as this report was based on a Google translation of Faliszek's interview with the PS Blog, we've mailed Valve to confirm the details.
