Streaming service Gaikai has always had a different business model than OnLive; instead of a direct-to-consumer platform, Gaikai wants to get you into a demo as effortlessly as possible. If you like what you play, the "Order Now" button is happy to connect you to a retailer. As a part of that mandate, Gaikai founder Dave Perry was "excited!" to announce that "Gaikai is the first ever to power 3D Games (FIFA 12) on YouTube." That would be the same YouTube that streams a bajillion videos of whatever to people every day.
If you follow this link and click on the "PLAY THE DEMO" banner above the video, you can see what all the fuss is about for yourself. When you're done, take a few minutes to remind yourself it's still 2011, and you weren't controlling the game with a bioport installed on your spine. The future is still a long ways out.
