More Secrets?

Strange that in just a couple of months the Wii will probably be released and we really know very little about it.

The XBox 360 has already been released and the PS3 is about to.
Why is Nintendo so secretive about the specs of the Wii? It has already revealled the controller. Surely - unless there is another secret - there is no reason not to show us the final specs.

Anyway just my thoughts
