What I'm hoping for is some cool integration for content creation, if there is a way to record high quality footage without stressing my computer out or using OBS that would be fantastic, especially if you play through your PC browser.
I would also love if STADIA did something cool to help promote their founders through youtube, it would be a great way to build their brand if people actually see other gamer enjoying the games on their product.
I think the main draw for me when it comes to cloud is playing a game that doesn't stress my PC out and gives me the option to record the footage or stream.
I also hope Stadia/OBS work together so it's easier for OBS to pickup STADIA gameplay for recording or streaming
I would love to see Mixer integration.
