Whilst Valve have previously criticised the console for it's architecture, now they're just saying that they need new people to code for it. Talking to Joystiq at a Left 4 Dead 2, Doug Lombardi said;

'we have to get people under our roof who are dedicated, talented PS3 guys and then all bets are off. We can take the same sort of strides and get the quality out of the box and offer the same support post-launch on that platform, as well.'

Nice of them to see sense - ignoring a market so large would be a stupid mistake. So could this mean Left 4 Dead 2 PS3? Well, probably not, though we suppose a late port could be possible. Left 4 Dead 3 PS3, however, is much more likely.
