I had been saying this stuff for awhile to family based on lil updates on the back end like their x86 emulation and when i first heard about waydroid integration it was so obvious they planned to make quest games easily ported over, its fuckin awesome, everything i expected and i couldnt be happier. i would love to install steamos on my quest 3 if its ever possible lol idk why i said implementing waydroid into proton and emulating quest games tho obviously ik thats not how either works i think i just mispoke in the excitement lol waydroid is implemented into steamos and quest games are natively ran through it obviously.
that quote is about steam being able to put android apps available on google android phones, they do plan to have android games on steam but it seems like not android apps themselves although people could get aurora store anyway i suppose.
