It's the first announcement... I think people are expecting far too much when it's the first official announcement of the console. As BoB said - they have a full year or more to drip feed us information.

One thing I'm curious about is that game controller. It's got a touch-screen on it's front, plus a very play-station move like Light bar over it's top.

It will be interesting to see how it will be used in the future.
