I wouldn't count on many developers going back to update old games with ARM support. It's more likely that the community will work to build some sort of Box86 + Proton stack to get games working, which should get a lot of the classics working[0]. From there, I think the struggle will be getting Box86 to run fast enough for modern games. Apple's ARM CPUs have great IPC, but that can still get annihilated when it's forced to simulate SIMD/AVX instructions. I assume Apple has some sort of vector acceleration framework in Apple Silicon, but it will take time and effort to reverse-engineer and implement.
Things are certainly looking better than they did a couple years ago, but getting ARM to run x86 code faster-than-native is an uphill battle. Maybe even an impossible one, but I've been surprised before (like with DXVK).
