I still doubt we will see a desktop Linux port. Especially after what Canonical pulled in terms of 32 bits support and the controversy that followed. Support costs on a small and fragmented ecosystem will be a problem.
Oh, great confirmation! So CDPR are now going to be making Linux/Vulkan version of CP2077 (for Stadia)! Which I suppose means hiring Linux developers, gaining Vulkan expertise and all jazz. That's huge.
@Marcin Momot: what about the desktop Linux release? Now you have very little standing in the way of it.
I don't think Canonical has any effect on this. And 32-bit support has no bearing on any upcoming games.
