Valve made a lot of noise at Sony’s E3 2010 press conference when studio founder Gabe Newell took the stage and announced that Portal 2 for PS3 would ship with Steam support, implying that users of the PS3 version would have access to the usual suite of Steamworks features, including the Steam Cloud, achievements, and various friends list functionalities. And, yeah, this is all true: in a press release floated by Valve this afternoon, the studio detailed all of the stuff you’ll be able to do in the PS3 version with a connected Steam account, specifically stating that users, via a version of the Steam UI overlay, will be able to access their Steam friends list, chat with other Steam users, accept and send game invites cross game, view Steam achievements, and send their save files to Steam's cloud for PS3-to-PS3 transfer.
