Valve to Bring Steam to the PlayStation 3 Next Week

I realize this news isn't specifically RPG-related, but it has huge implications for the way we'll purchase and play them on both the PC and Sony's consoles in the future, so it's certainly worth pointing out. Valve has just announced that they'll be bringing their popular digital download service Steam to the PlayStation 3 next week, with the first supported title being their Portal sequel.
Portal 2 for PlayStation®3: Steam Details Revealed

Valve's Highly-Anticipated Title Prepares for Launch On PS3

April 13, 2011 - Valve, creator of best-selling game franchises (such as Half-Life, Portal, Left 4 Dead, and Counter-Strike) and leading technologies (such as Steam and Source), today disclosed details regarding the Steam experience designed for the PlayStation®3, which is set to debut next week with the release of Portal 2.

The first title to support Steam on a console, Portal 2 offers cross-platform matchmaking, gameplay, friends, chat, and achievements, all powered by Steam. Steam on the PS3 also saves co-op game progress and single player saved games to the Steam Cloud, enabling players to pick up where they left off on any PlayStation®3.

The Steam overlay for PS3 provides access to both PSN and Steam friends, displaying their in-game or online status and providing a quick pathway to text chats, player profiles, friend requests, and game invites. Steam Achievements are earned in lockstep with PSN Trophies and are also accessible within the Steam overlay.

Steam on the PS3 provides access to all of these features once the player has linked their PlayStation® Network account with a Steam account, which is done right within the game. A Steam user can login to an existing account, and anyone new to Steam can create an account with the click of a button.

In the spirit of Steam Play, linked players of the PS3 version of Portal 2 can also access and play their copy of Portal 2 on any PC or Mac by redeeming an in-box access code on their computer. The Steam client verifies the linked customer and then lists Portal 2 among their library of Steam games for PC and Mac.
I see a bright future with Steam on consoles, particularly because it will likely encourage more developers to properly support the PC with their releases. Will there be a day when my entire Steam collection is downloadable and accessibly from any PC and (keyboard-supporting) console in my house? I hope so.
