Is stadia going to be supported on google nest hub and if so when?
When is stadia coming to nest hub
As far as I know it's not supported currently, because according to the requirements you can only play Stadia on a PC via browser (stadia.google.com), on a mobile device via Stadia app or on a TV via Chromecast.
It's a good idea though, would be nice to be able to play Stadia on a Google Nest Hub. Maybe it makes sense if you can leave this as feedback to the developers, to make them aware? You can do so by clicking on your profile picture in the top right corner (e.g. on stadia.google.com or in the Stadia app) and select "feedback".
yeah it would be nice to combine the functionality of voice commands and clear display and sound with stadia. I think theyre not far from getting it right.
