Proven fake, check it out HERE. Thanks to Simon for the heads up!
Wow, this really brings me back. This story reminds me of my days working on the old blogger site! Back then we had no idea about the Wiimote, nor the graphical capabilities of the Wii. Because of that, rumored screenshots from Wii games would pop up ALL the time. Well now some more of those pictures popped up on a German Wii site. They are claiming that these pictures come from Miyamoto’s new project that he has been working on. Take a look at the pictures below, and make sure you have your grain of salt with you! Thanks to Marcus for the heads up. In my opinion, they don’t have a very Miyamoto-like design.
