Considering the trend seems to be a move towards ARM (see Mac M1, Windows on ARM + Window’s ARM translation layer) - I wouldnt be surprised if they do exactly that, eventually.

There’s already some work that might lead to it. As ARM gains prevalence, I think it’ll happen sooner rather than later - once all of those dependencies do all the hard work. The efficiency of ARM for mobile devices like the Steam Deck really just scream for it
