It is a rumor, hence the ?, but look at this.
Left 4 Dead 2 Search Games - Video Game Browser - EA Games
EA lists it for PS3 at both spots, listing it as a Fall release along with the 360 and PC version.
Valve doesn't like the PS3 architecture, so they aren't too fond of developing for it, but we all know that EA ported Orange Box to the PS3. Despite the fact that it was a pretty BAD port, it seems like EA might port Left 4 Dead 2.
So I suppose PS3 owners might have something to look forward to. If it is true, I couldn't imagine the port would be as bad as the Orange Box since they have had a lot of experience with the console since then. Mirrors Edge is considered better on the PS3, and Dead Space is pretty much identical, while they both run fantastically.
Edit: They just took it off their website. So either mistake, or accidental leak. I will probably go with the former, but I am not sure. Listing it for PS3 is one thing, but putting up a PS3 box art for the game is another, lol.
