Everything will end up on PC. Microsoft will have their games playable on all windows devices from tablets, to PCs, to laptops with scaling to the specs of that machine similar to how the performance of Switch games in home to portable mode. Also expect MS to sell more windows systems and call them xboxs. I also see them making xbox live something that will need to be payed for on PC because it brings in a lot of money and can't see them ditching that xbox live money for a while.
Nintendo I think they will make more tablet like systems in the future that can be docked and played with better performance on TVs. Also could see them having a PC service with monthly fees to pay games from their older consoles.
Sony I think will try to get PSNOW on as many systems as they can. I could see them continue making consoles for a while and then transition to a download able PSNOW games and making games on PC.
