New Dragon Ball manga (spin-off) confirmed. Akira Toriyama's new project is entitled Dragon Ball SD and was recently confirmed on the new Saikyou Jump by ShonenJump.com. http://shonenjump.com/j/news/detail101108_2.html
If you can't read Japanese:
The spin-off series will be in color and entitled Dragon Ball SD, and will be created for the magazine by Naho Ooishi, who previously did the two-part manga adaptation of the 2008 Jump Super Anime Tour Special. There is no word yet on whether or not this will be a one-shot or an on-going series.
Saikyô Jump debuts in Japan on 03 December 2010, so we can expect all sorts of new information very soon. Coincidentally, December 3rd will be the manga's 26th anniversary — the first chapter of DragonBall debuted in 1984's Weekly Shônen Jump #51 on that day. Very exciting news, folks! - http://www.daizex.com/
