They probably will. It seems to me that the market is going to produce Sports games and FPS with the odd Warcraft based film-inspired or sequel RTS if they can be bothered.
Personally I'm tired of it. They've picked a genre and they are just upping and upping the targets to isolate and force upgrades. I can cope with those targets no problem, but I feel sorry for those who can't.
XBox version I don't have a problem with, after all, that's a game console, but I'm seriously losing faith with the PC market, which should, by rights, have far more flexibility.
