Famitsu is reporting on a Wii game coming out on the 24th of May in Japan.
A rough translation of the title reads: "Sweeping, Cleaning Squadron, Oh I Come!"
Judging from Google's translation and the pictures, this will be a Echi (or erotic) game. There's also talk about "CG Rewards" (translation FMV sequences) for completing certain tasks. As far as I know, there aren't many of these games released by Nintendo.
Nintendo seems to be letting this one slip through. Or is it just because it's being released in Japan?
Will the west also be seeing this kind of game in the future? If yes, I hope they change the supposed "High school girls" that feature in all these games, to the Japanese equivalent of collage girls.

has some teaser videos, if you are willing to click around the moon speak, flash site.
