I think only a fraction of existing games will be ported. However, now there will be a much stronger incentive to use cross-platform engines in the future. It used to be "windows + mac port" for a lot of games. "windows + mac port + linux port" sounds silly, so the obvious solution is to start with something that already is cross-platform. Wasteland 2 chose Unity engine because it's so cross-platform. It even has unpolished Linux support. The Linux port of Unity hasn't been released, because developers were doing that in their spare time and it wasn't up to Unity creators' standards. Now, InExile has been given Unity source for purposes of creating a decent Linux port. It's a single anecdote, but it illustrates what I'm saying above. Makers of Unity will probably want to get the most out of it, so Linux port of Unity will be contributed "upstream" and it's very likely that Unity will support Linux from now on.
