They aren't bashing on the PS3 because they like to. They keep talking about it because people keep asking them about it. When the interviewers ask them about the PS3, naturally they are going to respond. Thats the way a damn interview works. Valve has never gone out of its way to say the PS3 sucks; interviewers constantly ask "When are you going to develop for the PS3?" and "Why do you not like the PS3?". Well no shit they're going to say something bad about the PS3 again, they're being asked about it and their stance hasn't changed. It is an easy way to get your site views. Obviously, it's worked here. Though I do think his statement was incorrect but hell, they obviously don't follow the PS3 anymore because they don't want to.

The community is so split between saying "give me xx on the console!" and "Valve sucks at making console games". OB on the PS3 was relatively terrible compared to the other two and it's always been clear that Valve is PC first, and with the 360 being relatively similar compared to the PS3 it's a much easier decision. PoweredbyHentai (mmm) made a decent post arguing against Valve, but I ultimately have to disagree with what was written for 2 reasons. The first is that they are a company; and not only that, they are a mainly PC company. You wouldn't expect a huge PC company to do it's utmost to improve the community of another platform unless it fully had plans to migrate a large amount of resources to it. When I feel Valve refers to the community, it's talking about the PC and 360 community, not the PS3 community because that's their target demography. The second is that the actual amount of resources Valve has is debatable, at least from what we've seen. Take for instance the development and release of L4D2. Over the past few months we've seen large amounts of resources from their other IPs be drawn away in order to work on this. Their content, though usually high quality, comes out at the pace of a snail. The very informal nature of their company dictates that a lot of the time their leads spend is on PR. The actual manpower available in Valve has been something I've always been curious about.

Finally, note that they posted this before they even posted the interview where it was talked about ("Look out for part two of our interview soon."). It was obviously meant to ruffle some feathers by taking it out of context. Learn to read deeper than the words being spoon fed to you. I don't agree with what was said, but this comment was obviously taken out of context and reported in a way to turn heads. Valve really shouldn't even be approached about the PS3 anymore because their stance is pretty damn clear; journalists just do so in order to rack up attention.

Edit: I wrote this because I've seen a lot of Valve hate because everybody thinks that they just bash the PS3 for fun. People don't understand that they aren't exactly grabbing the microphone from people and shouting that they hate the thing. I think their stance is kind of dumb but they at some point decided it wasn't worth it. In that case I'd really prefer they just keep their hands off the PS3 instead of releasing some shitty ports that piss people off even more. Same way that I feel IW should have just not released MW2 for the PC at this rate. Which I find kind of sad that some people here who bash Valve for statements like this also praise IW for it's "improvements" to the PC version.

Edit 2: Why do people keep saying that Valve is "proud" of their inability to properly code for the PS3? In the past they've stated they don't like the architecture and they don't feel the time-cost was something they'd be willing to spend. That's pretty much all. That doesn't make them proud...? Or am I missing something here?
