Dark Souls 2 sold probably more on PC as on PS3 or 360 first week in western countries if we look at 80k simultaneous players day one.
That's not AAA but PC sales would be obviously even better without consoles.
Games like Diablo 3 sold what? 8 millon the first 6 months or so?
I think some games couldn't live on PC but games like The Last of Us would have very good sales. But we have the same situation vice versa. Something like Starcraft would be never that successful only on consoles...
