unlikely because Lana doesn't like DRM and needs a special deal for games that have it i.e, "allow us to turn this fucking crap off while playing"... Gog has such a deal with Larian which is why bg3 is there but the 'plain' was Stadia and that went to shit a while back
now as it stands Larian has crossplay listed as 'we will get to it some day' which means it kindo works on Steam to Steam or Gog [Galaxy to Galaxy] but you can forget PS, xbox, Mac and cloud until they make a STABLE build sometime next year at best because no one is willing to build interfaces when the Mac build is different to the PS build
