I think it's the future of gaming. Full HD game-streaming and perfect FPS will be in the near future (10-20 years?) in the western world. I also think Steam, Origin, Ubisoft, Gamersgate, ... could use this technology too, but there are hardware and pc sellers on the other side. Who needs new pc's and better hardware, if a streaming company can stream to you every game in ultra high settings and with perfect FPS.
I also think game-flatrates get more progress in the future. You pay for example 30/40/50/60 euros every month and it depends on how much you pay, you can play older games or newer games as much as you want. There is a german company offering this service. You can play games which are 1-2 years old as much as you want, but not every gaming publisher is supporting it, therefore not every AAA title is available in the flatrate.
I am sure that game-platforms like Steam, GamersGate, GreenManGaming, Origin, ... will somehow change their way of distribution and I think game-streaming will become more important.
