One thing in the works is game studio subscriptions. UBISoft has this already and I've signed up for 14.99. Right now it is only supported over Luna (Amazon's streaming game service) but Stadia support is coming soon. For large studios this model makes a lot of sense. I would use it for EA Sports as well. I don't need to "own" the game, but I do want to own a relationship with the publisher that will let me play their game anywhere. It'll be interesting to see how major consoles react to this where licensing doesn't really let publishers give their own direct user's access to titles on the console. I can see game streaming being a big win for publishers and a big loss for consoles which are essentally middle men.
