I so very much hope that the Linux gaming effect increases. Not only for gaming, but for the productivity world. If development of these 'compatibility layers' (Wikipedia) like Proton, Wine improves and maybe win-native software (thinking of CAD in particular) can be made working reliably on Linux using these packages, one or the other big player might adapt. That would be a much cheaper way of expanding the software's range than developing and maintaining a native Linux port...

... and maybe I am too naive.
