@endimiion,
There is truth to what you say, but I don't see how any of it means we get to say that games like UT3, Bioshock, and others are exclusive, or why we shouldn't talk about their PC counterparts..
The comparisons are easy to make as long as you aren't trying to compare the games sales numbers cross platform. We all know what kind of control scheme the PC and xxx console will have for a given game, so its not like we can't compare the merits of the control scheme and judge for ourselves. But more importantly we should be taking into account the fact that people probably aren't going to buy a console for a game they can already play on their PC. So while you can't compare the sales numbers, its not like it is hard to see what kind of impact a PC version will have on a game's ability to push consoles.
