This is potentially interesting future news: Team Ninja's Yusuke Hayashi, who is directing the re-remake of Ninja Gaiden, would maybe be okay with making a Wii game or whatever. If he had a good idea for one.
"There are several groups within Team Ninja. The PS3 group, the Xbox 360 group, and there are Wii fans in Team Ninja." At this point, any new Team Ninja game is, statistically speaking, most likely to be a port of either Ninja Gaiden or Dead or Alive 2. If you like either of those games (and why not?) then you can probably look forward to one of them on the Wii!
