New pictures have hit the web showing the evolution of the Revolution controller and nunchaku device, along with a first glimpse at the back of the console...

Pictures from the Japanese annual report book given out to shareholders have surfaced online. Below are two of the most revealing pictures, firstly a set of prototype Revolution controllers (some designs never even being made properly, staying in their clay testing stages).

Secondly, there is a picture showing the previously unseen rear of the Revolution prototype (we want to know what all those ports are for!). These pictures are rather unique, as Nintendo rarely shows off images of its consoles in their prototype stages.

For more scans from the report, check out the thread on Gaming Age here. There's some interesting conceptual drawings from a couple of well-known Nintendo titles.
