Toei & Co. are gonna be holding a major touring fan event all across the US and Canada this summer, starting with San Diego this July. For more information, hit their site.
Excerpts from the Dragon Ball: Super Exciting Guide put out in 2009. Has a lot of interesting minutia that the fan artists and fanfic writers will no doubt appreciate, as well as some pretty cool trivia, an explanation of how the DB Cosmos and Freeza’s empire ran, some background on Namekians and the aging process of Saiyans, and what the Dragon balls would feel like to touch.
Slight disclaimer: As of BoG/Super, I’m not entirely sure how much of the Kaioshin explanation still holds up, but I’m also not sure anything said here is contradicted per se. That said, Toriyama’s bound by nothing but what’s in the series, so I suppose he’s entitled to change his mind too.
But again, I think it still checks out, at least mostly.
