Valve has not excuse not to develop for PS3 anymore. And using "the PS3 is hard to develop for" hasn't been valid since like 2007. Infinity Ward proved you can make a game on PS3 just as good when Modern Warfare was identical to the 360 version.
And you also can't say its not worth the effort. There's nearly 26 million PS3 owners now and could be as many as 28-30 million by Jan 1. Its only 7 million behind the 360 and that gap is shrinking every week.
