Could the Wii-mote design have undergone yet more changes? Check out our image inside...

We know Nintendo have, in the past, tinkered with the final design of their controllers right up until the very last moment. And, post-E3, it looks like Nintendo have done it again. In the August issue of Nintendo Power magazine, a Japanese woman is shown holding what looks like no other Wii-mote we've seen.

The picture appears to show what looks very much like the GameCube controller's purple "Z" button on the underside of the remote. And, though it may be just the angle of the picture, the underside of the Wii-mote seems to be more curved at the end than we're used to. Could this be just a prototype? What do you think?

Big thanks to R-E reader Simon Ellefsen for sending in the picture.
