This is NOT the future, at least not the NEAR future. And by near I mean anytime in the next 10 years or more. The basic problem is that you'll never be able to push enough information through the bandwidth pipe to compensate for everything that your hard, drive, ram, processor, and video card can do for you. Consider someone who has their WoW settings up to a good level, but not maxxed out, which is most of the people I know. In order to recreate that same level of graphical beauty, you'd have to have a HUUUUGE bandwidth pipe. And all the internet servers in between you and the game servers would have to have far BIGGER capacities than that. What if 10 people on your block are playing WoW through a server like this at the same time through, say, DSL. Does anyone really think the phone company is going to install tons of very high end equipment just so 10 people can play a game?

No, there are FAR too many arguments against streaming gaming content. Steaming applications like microsoft Word is one thing, high quality games is very much another.
