This ought to make for an interesting discussion.
This could be little more than a decent piece of PhotoShop forgery, but it already has people talking: could last year's fantastic survival/horror shooter be coming to the PlayStation 3? Developed by Valve and distributed by EA, we wouldn't be surprised in the slightest if Microsoft had purchased timed exclusivity as they did with Bioshock . Furthermore, even though Valve may heavily dislike Sony's machine, EA's only bias is towards money, which means they probably aren't too keen on the idea of passing up the PS3's user base. This evidence comes from a N4G forumite by the name of "Graphics Whore," and you can find the other pictures here . Obviously, it shows L4D in a PS3 box, but we figure if such a thing existed, wouldn't we have heard about the impending release already…? But even so, the claim is that you can pre-order the PS3 version from Best Buy (see the pre-order card in one of those pics), and so, everyone is beginning to wonder. Third-party exclusivity is mostly a thing of the past these days, and unless a certain company decides to buy the rights to timed exclusivity, most titles end up on both the PS3 and Xbox 360.
And remember, it wasn't long ago when someone spotted Left 4 Dead PS3 on a UK retailer's site, although it was promptly removed. We'll keep an eye on things to see if an official announcement is forthcoming. For now, this is only a rumor so don't go around stating it as fact until we see something from either Valve or EA.
