So much panic over nothing...
The thing about TV, and movies is that we went from having to wait for a broadcast to just watching it whenever. We went from shows not being popular enough to put on cable, to shows finding their audiences through the internet, and services like crunchyroll.
TV got better because internet distribution replaced timed broadcasts. Games already saw the benefits of that once digital distribution became big years ago. That's where all these great Indie games came from.
How would the option of being able to stream a game give us more games? How would it give us more options?
