On the 7th of April this year, Nintendo registered trademark #2009-026024 with the Japanese Patent Office. For something called "Wii Fit Plus". Hrm. What ever could it be?
The mind boggles.
While companies trademark stuff all the time that means bupkis, we're a little more interested in this because it has a nice, formal logo attached (pictured above). Which tends to suggest that, far from being a "crazy idea" patent, this is something that Nintendo are actually working on.
Oh, and if you remember, April is also when something called "Wii Fit Plus" started appearing on the databases of European retailers.
