I wonder whether, when the faster Steam Deck 2 comes, it may have ditched the x86 architecture altogether and leapt to a high-performance ARM CPU, yielding more power per watt and generating less heat. If so, that would presumably require Proton to be supplemented with a Rosetta-style translation engine that can convert x86 machine code into ARM.
Currently, outside of Apple’s proprietary M/A-series CPUs, there don’t appear to be high-performance ARM CPUs that would fill such a role, though this probably won’t still be the case in a few years.
I’d say while it’s possible it’s unlikely, remember that they’re running PC games, all based on X86, the work needed to make Wine/Proton run all of that well on a different CPU set is significant, and would likely break compatibility in unexpected ways, effectively bringing all the recent wins moot and bringing Proton backwards. Definitely something that will likely happen, but more of a long-term goal (unless it’s already in progress and with advances, no idea, but we would all have heard of it already if it was a thing)
With the timeframe this is likely to happen over, it might be RISC-V instead of ARM since that’s an open source hardware platform and ARM seems to be joining enshittification trends (starting with worse licensing terms)
there already is a project for x86 to ARM translation on Linux called box86, and there’s another one for x86_64 called box64
havent heard about them in a while but I remember seeing a video of someone playing doom 3 on a raspberry pi with it so it seems very promising

There allready is a transition layer that can be used so they wouldnt have to start from scratch. Box86/64
A few months ago I remember they hired a contractor for arm development, I think they were a member from the Asahi Linux project
