OpenGL is becoming a lot more popular lately with game developers. Maybe Microsoft plans to migrate to OpenGL as the primary graphics system for their platforms.

I must have missed that. Perhaps if you enumerated a couple of AAA games from 2012 or 2013 on any major platform (by which I mean PC, PS3, Wii, Xbox) that chose OpenGL that would help make your point that OpenGL is popular with games developers.

Maybe Linux plans to move to DirectX. Who knows?
