It seems people are forgetting that the PS3 version has mouse and keyboard support so that won't play that different from the PC version. Hate to annoy the depressed PC gamers even more but the 'huge' advantage over PS3 players in case there is cross platform play is very minor if present at all.
Can't blame PC gamers for being pissed, every great PC game (almost) also gets released on consoles and consoles get other great games that never get PC releases. It's like consoles are getting the best of both worlds. And now with keyboard and mouse support coming to PS3 and 360, future console RTS and FPS should be as good as PC versions.
