"Bandai Namco might be working on its third Taiko no Tatsujin for Wii U. A new domain name on the publisher’s Japanese website, which should be updated once an official announcement is made.
You may recall that Taiko no Tatsujin Tokumori was leaked in a similar manner. Soon after its domain name was discovered, Bandai Namco unveiled the title."
Won't move any hardware in Japan, but it's always good to see more games announced. Hopefully it sells more like the first game though instead of the second. This also makes me wish Nintendo would make some games like Rhythm Heaven for the Wii U since I find that it's lacking games of that genre here in the west.
