Wish I knew, but this reminded me to take a peek at
http://www.michikotohatchin.com/ , and it's been updated!
The intro Flash has a couple of different background/costume combinations when redisplayed (I only managed to see 3). There's also a character, story, and staff page (which I would love to see translations of, hint hint)
The top pic on the right of the Story page has me laughing. The attention to details in the backgrounds gives me hope that it's going to be something I'll enjoy a lot -- I already like the style that's evident in the characters and the teaser -- so it should be fun.
