Valve has announced that the PlayStation 3 version of Portal 2 will feature Steam functionality. This is the first time Steam has ever appeared on a console, and this will also be the first time that PlayStation 3 gamers will be able to play with PC or Mac gamers. Along with cross-platform multiplayer, we can expect persistent cloud-based storage for PS3 save games and cross-platform chat. (To clarify, "cross-platform" in this context means PS3-PC/Mac, not PS3-360.)
On top of that, anyone who buys Portal 2 for the PlayStation 3 will be able to unlock a Steam Play copy of Portal 2 for the PC and Mac for free by linking their PSN and Steam accounts. Portal 2 project lead Josh Weier explains that Valve has designed the cross-platform experience to be hassle-free: "PS3 gamers will be able to simply drop the Blu-ray disc in the PS3, link to their Steam account from inside the game, and all their Steam friends (on PC and Mac) will be visible and accessible for chat and game invites."
Back at E3 2010, Gabe Newell promised that the PlayStation 3 version would be the best console version, and now we know what exactly he meant. Newell went on to say, along with today's announcement, that Valve hopes "to expand upon the foundation being laid in Portal 2 with more Steam features and functionality in DLC and future content releases."
Portal 2, one of our most anticipated PS3 games of 2011, will be out for PS3, 360, PC, and Mac in April.

But seriously, this is fantastic. I am going to play on PC, but I may buy the PS3 version just so I can have to copies for the price of 1 :p Unless PC version is much cheaper.
Well, almost anything.
Your theory hits a wall when you consider that
A) The PS3 version has split-screen
B) It comes with another copy of the game
C) You're relying on the idea that all PS3 owners have enough disposable income for a gaming computer.
However the cross platform gaming aspect does. That is pretty neat. I just wished they had done this (or Microsoft had allowed them) for L4D on the 360/PC. Seriously, that would've been awesome.
Besides what VGFreak1225 said, it's also the best version because you can play cross-platform with PC users. And "I can't see ps3 users really wanting these features" makes absolutely no sense because you don't even know all of the features included with Steamworks for PS3.
You complain a lot.
In other news, i see myself pre ordering the ps3 version: if anything that's a way to get a physical copy lol
Is this what it feels like to be a PS3 owner the other 99% of the time?
I have l4d2 on PC, but I want to play it on 360 too, surely I own the license to do so?
With this here news we're 1 step closer to the future I want to game in.
Very nicely done valve. Very nicely done indeed.
I still don't know with all the hackers on PSN though. They'll find a way to fuck it up for everyone.
Cross. Fucking. platform. This is actually a major step in gaming, IMO.
@Haters: Y'all guys just hatin', yeah? Yeah. This is brilliant. At the end of the day; Steam is becoming its own thing. It's a shame that it's not on the 360 too, but that will come in time.
I'm just excited to play with my friend in preston.
who you talking to? nobody said anything! (Besides me saying Steam to take over PS3)
2) Activate on my PSN account
3) Download Steam version
4) HAPPY BIRTHDAY BRO. Portal 2 for PS3!
Win freaking win.
