Ah, Viz. Ever the eternal tease. From their panel at NYCC, they announced that they've licensed a new series from Rumiko Takahashi, and that it'll be awesome, but are keeping the information about the title itself on-the-mum.
To fill out the rest of the Viz panel, I'll be relying on Gia's liveblog of the event. Some of the other bits from the panel were that the Detroit Metal City manga will be coming out in June -- the Japanese manga is sitting on my desk right now, actually -- and Yu-Gi-Oh! R will be coming out in October.
It also looks like the Monster anime will be coming here "sooner than you think," according to the Q&A at the Viz panel. There are several other titles in their release schedule, like The Gentleman's Alliance Cross artbook and Butterflies, Flowers are just some of the items cropping up.
Be sure to take a look at Gia's liveblog if you're interested in some of the other announcements. There's plenty of Naruto news that's in there!
