Valve is sorry for its past transgressions against the PS3, like an outsourced Orange Box and complete lack of Left4Dead, and intends to make up for it by making the PS3 version of Portal 2 completely awesome. Not only will the game come with a free code for the PC version of Portal 2 and cloud saving, but it will also offer Playstation Move controls. I haven't used the peripheral for pointer controls myself but I hear they are as accurate as Wii pointer controls, which makes this quite an excellent proposition. If you own a PS3 this is definitely the version of Portal 2 you want to get.
Update: Valve has now stated that their employee was mistranslated, the game will not support Playstation Move
