I disagree. While that may be true for most AAA shops there is a trend at least with indie developers and some larger companies in adopting Linux/OSX. Case in point is the fact that Valve’s SteamOS uses Linux and has sunk a lot of time/money into porting their games to it.
While my library is largely indie titles, my Linux compatible games are greater than 75% of my total library. Mostly AAA titles making up the windows-only and somewhere around 80-90% being OSX compatible.
I have hope 
I guess in the meantime I can dig out my old copy and pretend it’s been updated. :\
