Valve has already sent support for the new Steam Controller upstream: https://www.phoronix.com/news/New-Steam-Controller-SDL


It will be able to run android apps, any steam games, and because it’s going to run Steam OS, you can run lutris or heroic launcher as well. So emulation and a whole variety of older games.
Also because it’s a stand alone, but can pair to a pc, you will be able to work straight on it with KDE desktop and whatever applications you want to run.
