You're either underestimating revenue from Windows purchases or overvaluing that publicity bonus. There are already a lot of indie games with Linux support, and triple A developments already sell millions of copies. If that added publicity made another 1000 people buy the game, it still won't be a financially sounds decision.

Heck, I'm mostly on Linux but boot into Windows for gaming... I'd probably continue to do so, even if the games were released for Linux just for that extra performance and significantly less chance too run into an obscure issue with my setup.
