If currently Linux has 1% gaming market share, I am thankful they port these games at all. I am one of those early adopters that paid >$1200 for a top end Steam Box, and bought every single AAA game available on Linux even if I might not play them all, just to put my money where my mouth is and perhaps contribute a bit to getting Linux more relevant. It's only going to be because companies will see some money out there as well, so I try to give them what they want.
