I'm really excited for the GabeCube, even if I don't actually get one. When the Steam Deck came out, all of a sudden there was a huge incentive for AAA studios to start finding bugs that affected Linux/Proton use, plus a huge new push for community-driven hacks to make things like FFXIV work well under Linux.
Simply having more momentum behind gaming-on-Linux means it's harder to ignore Linux support.
