The Linux world keeps resisting the introduction of a standardized API because they assert they aren't needed. Certainly with Steam putting out a platform exclusively for Linux they seem to have a point. But the gaming industry is sufficiently invested in programming for the Windows API that they don't seem interested in changing any time soon.
