In addition to Wii Fit Plus it looks like Nintendo may have some other surprises like Art Academy. An trademark for that title was also registered. Is Art Academy going to be Mario Paint for this generation or is it going to be a bite sized DSiWare game? BonsaiBarber is rather enigmatic too and at a first glance it sounds like something just for Japan. However, the trademark, even though it’s on Japan’s database, is in English.
Update: Like many commenters pointed out Bonsai Barber is already out on WiiWare in North America. The Nintendo trademark is likely a sign that Nintendo of Japan will publish and localize the game similar to what happened with World of Goo.
