Re: It's unlikely to improve
"The reason it *is* likely to improve is because it's becoming less and less common to write games entirely from scratch, which need to be ported by hand. Instead you use a pre-made engine of some sort, which has support for multiple platforms out of the box, so the "porting" has mostly already been done for you."
The likes of EA, Activision etc. have in house middleware engines for their games. Even if they ported those engines to Linux it doesn't mean that porting is as simple as a recompile. Go look at the credits of some game and there might be as many or 30 or 40 people working on a single platform and hundreds in total. It all requires development effort, testing and continual support. Why do you think so few PC games get ported to the Mac let alone to Linux? It's because the potential return isn't justified by the effort.
As for indies, yeah they could use Unity or similar, assuming they fork out for the Pro version. It still costs time, effort and money to test and support that platform.
