As expected, the PS3 version of Portal 2 will feature full cross-platform compatibility with the PC and Mac versions of the game. According to a recent press release, PS3 owners will be able to chat and jump into matchmaking with PC and Mac users, and they’ll also be able to save their game using Steam’s cloud-based service, ensuring that progress is never lost when switching platforms.

And speaking of different platforms, the PC and Mac version of Portal 2 will also come free to PS3 users who link their PSN and Steam accounts, much like how the Mac version of a Steam Play game comes free to PC owners.

Awesome!! Another reason to get a PS3.

Wow...thats so cool!

That is actually really cool.

If I could preorder PS3 games to get hats for TF2 that would be amazing.

Valve...I heart you.

This is pretty damn fantastic, I hope this becomes a new standard.

Holy Fuck, Really. This sounds awesome!

A bummer for us XB360 owners! :-( Good on Sony for being open though!

Had planned to get it on PC but if it comes with the PS3 version I might aswell get that. I think Portal 2 with Move support would be the thing to push me into picking one up, get on it Valve.

Neat! Be even better if I had Steam on a computer that could run Portal 2, but then, I wouldn't be buying the PS3 version, now would I? But now I can play co-op with my PC owning friend(s) now. 

Nice. I never thought Sony would let something like this happen.

This is the future of video games, not one console, but mutiplatform compatability.

Sold.

This is cool... but won't the PS3 controller severely limit the abilities of the user, compared to the PC user? For instance, you can play Portal much faster on the PC because of KB/M. Consoles take a little while long because of the nature of analog sticks. So that brings up the questions of the equality of control between one person playing the PS3 and another playing the PC in a multiplayer session. 
 
Personally having no care in the matter of multiplayer I'll be picking this up for the 360. Even if I wanted to play it online it's not like there'll be a shortage of people online anyway.

3 versions for the price of one sweet.

 3 way Steam Play and cloud saves? Done and done.    

IMHO, this should be the future of all multiplatform HD games.  I get it on the 360 or PS3 and can play it on the PC as well.

Question: If I buy the PS3 version and I put the PC version on my brother's PC on using my Steam account, can we play coop?  Or can I only play one version at a time on my account?

This should be the future of home computers and consoles... games for all of them, compatible with each other, ensuring that players can enjoy them with their friends, regardless of what hardware they decided to buy.
 
Sadly, I don't see the major platform holders agreeing with me, deciding instead to splinter the userbases.

Don't have a PS3, but that's very cool of Valve.  Every PC/Mac player who has a PS3 would be best off buying the PS3 version. *thumbs up*

This is a big deal. Next step would be having all the PS3 saves in the Cloud. But for now I'll take this. May actually buy Portal 2 now to encourage this kind of thing. Well done, Valve and Sony.

and both versions are free to play oline too

Wow that is amazing. So I get it for PC like I was planning, and I can get it for ps3?!? What more could i ask for? 

This is AMAZING!!!  I was only going to get it for the PC, but now I'm getting the PS3 version with PC version!!! 
I <3 Valve!!!

afk, switching pre-order to PS3 version.  2 Platforms for the price of 1,   sold.

Awesome to the max.

Dilemna! I generally buy the 360 version of multiplatform games, but this sounds compelling enough to opt for the PS3 version. Only the person I'll likely be playing co-op with will only be able to get the 360 version. Nooooo......

I had been worrying that VALVe was kind of... "Slipping" with all of the DotA 2 drama and delays, but this made me jump right back onto the bandwagon (been on it since 1999 <3).
 
Definitely getting the PS3 version now! Do you guys think that if the PC version is linked to your same Steam account on PC (I imagine it has to be), you can play co-op with someone on that same account (PC) while you join them on PS3 (same account)?
 
Edit: not 2003, 1999 haha.

This is amazing! I'm definitely getting the PS3 version! I fucking love Steam.

The person who originally convinced me to play Portal only has a Mac, and I only have a PS3. The fact that we can play co-op together in the sequel is really exciting.

Interesting. Cross-platform is usually frowned upon because of the edge PC users have, but in a co-op environment this should be less annoying. Will be interesting to see how it works out.

OK, when does Sony buy Valve and make Steam be part of the ps4?  Obviously Sony is working hard on getting Valve's love.

I wonder if PS Move will work with Portal 2 similar to how the Razor Hyrda works?

Dude....that solves my dilemma.

Kudos to Valve for a killer cross-platform product. it almost makes up for their complete lack of understanding of what the "episodic" model is.... almost.

Man, this is a huge deal.  So when does the PS4 just become the Steam box? :D

Awesome, one less decision I have to make this year!

Yep, I still love Valve.

" A bummer for us XB360 owners! :-( Good on Sony for being open though! "

I wonder if MS will counter with buy on 360, get free on Games for Windows?  This would begin a new war...

Shouldn't really matter, since it isn't competitive.  "

This is why Valve is such a popular developer among gamers. They are not afraid to take great ideas and make them into reality with their fine products. Other developers should take a look at this and hopefully more games will feature cross-platform play in the near future.

" @mosdl:  I'm pretty sure Valve's games are only available through Steam on PC. That would be hilarious though. "
