Usually when someone describes a new product as "the same as x through y while z", it means the new thing is solving a pain point. Like, "isn't Heroku just git hosted on AWS which runs a Rails server after a push?"

The process you're describing is definitely workable and some games take advantage of it, but the Ouya focuses solely on making the experience of playing and downloading games painless. Whether or not they'll succeed is a different argument, but the Kickstarter proves that there's demand for such a product.
