Highly doubtful it would be a SteamOS exclusive. The OS is free and they won't be making money off Steam Machines (unless they do bring out their own, and then they wont be making much if they want it to compete with consoles), so there is no benefit for them to do this. Now a Steam + SteamOS exclusive on the other hand would make Steam Machines a more attractive prospect to console gamers and get them into the Steam ecosystem where Valve will get their hooks into them and make piles of money!Mr.K. said:Well let's be honest if they make HL3 SteamOS exclusive and launch both simultaneously that shit will hit the mother load of fans and then all the fans will buy up every damn SteamBox they can get... it's evil genius really.
That is how Steam took off in the first place, it would be quite fitting to continue that sneaky tradition.
And for once I'd actually prefer waiting to play the game.
