At the Electronics Entertainment Expo in 2010, Valve and Sony announced that the two found a new business relationship. Where originally Valve saw Sony's PS3 difficult to program for, they now praise it for its networking capabilities: an open peer-to-peer network that is free for both developers and consumers alike.

This symbiotic relationship lets Steamworks and the PlayStation Network to be one integrated entity: allowing Valve to continue expanding their market share, which they started with Apple's Macintosh, and Sony to have great games.
Portal 2 has already been announced for February for the PlayStation, but it doesn't make sense for Valve to pay programmers and developers to create Steamworks on the PS3 for only one game. So, obviously Valve expects to bring more of their games to the PS3. Left 4 Dead seems like the perfect title after Portal 2.
Not only does Valve have a great relationship with Sony, they also have a great relationship with Electronic Arts, by including EA games on Steam.
Left 4 Dead, an Xbox console exclusive, is published by Electronic Arts, who is completely console-agnostic and 110% profit driven. As you may have guessed, EA and Sony are also great business partners. EA recently announced the previous Xbox console exclusive Mass Effect 2 for the PS3 for February 2011, and was also heavily involved at Sony's E3 press conference: announcing exclusive bundles with PlayStation versions of games, such as the new Medal of Honor (including the original), and Dead Space 2 (including Dead Space: Extraction.)
This business model of bundling old games for a great value is seen ubiquitously throughout Valve, EA, and Sony's gaming lineup. Examples can be found when looking at the EA-published Valve-developed Orange Box which was a bundle of 5 games, and Sony's "collection" series, which consists of The God of War Collection, The Sly Collection, and The ICO/Colossus Collection.
Bundling Left 4 Dead only seems logical as it will catch PS3 gamers up to date, give them a great value, and redeem Valve's relations with console customers by updating the title while distributing DLC free of charge: something promised for the original Left 4 Dead.
In conclusion, because of...
1.) The PS3's blu-ray format that allows 60GB of space per disc.
2.) EA, Valve, and Sony's habit of bundling established franchises.
3.) Their newly strengthened business relationship.
4.) Valve's lukewarm customer response to the announcement of Left 4 Dead 2 instead of Left 4 Dead 1 support.
...it is not far fetched to assume there will be a Left 4 Dead bundle coming soon including Left 4 Dead 1, 2, and all of the downloadable content on one bluray disc that will be supported using Steam on the PS3 after Portal 2 debuts.
And if they haven't thought of it, with enough feedback, it WILL happen since EA, Valve, and Sony all directly listen to their customers.

It's a win-win situation for everyone: Sony, EA, Valve, and the customers. Everyone except Microsoft, but I'm sure they won't go bankrupt anytime soon.

Microsoft announced its financial results for Q3 of fiscal year 2026, including an update on its gaming Xbox business and more.
Not looking good. Hopefully Asha Sharma is able to turn Phil’s disaster around.
To me it's still quite remarkable how they can cash-in 5.3bn in revenue in a single quarter, since their hardware is basically dead.

The charity event will be streamed live from Gamescom in August.

Thanks to the slip-up of an artist working on the title, we now have more evidence that a new Injustice game is in the works.
One thing I will say, is that EA own the distribution rights for the physics copies, but don't actively publish it.
In fact, Valve might be better off releasing the games on PSN, no file limitations and easier distribution.
I sure hope Valve isn't working on a PS3 port of Left 4 Dead...
They've got much bigger fish to fry right now than porting two year old games to the PS3.
You people act like Valve is some run down company in a basement w/ around 5 or so people working on games.
Either that or you get caught up in the precious console war bs.
