The SimonSays website has been updated with new Viz releases through August. In addition to first volumes for some previously announced series, there are some surprises, too!
Ooku: The Inner Chamber - yes, this is the historical series by Fumi Yoshinaga!
Black Bird
Choco Mimi
Kimi ni Todoke
Children of the Sea
Gestalt
Waqwaq
Detroit Metal City
Rasetsu - sequel to Yurara
Tail of the Moon Prequel: The Other Hanzo - apparently this is really called Tsuki no Toiki
Other things:
* Slam Dunk seems to be going bimonthly after volume 2 finally appears in February
* Boys Over Flowers volume 36 appears in June, which concludes the series. No volume 37 (a short story collection) is scheduled for August, which doesn't necessarily mean Viz won't be releasing it, of course, but it won't be continuing the bimonthly schedule.
