Akira Toriyama is deeply involved:
"Itís rare, or I should say, itís the first time, that Iíve been deeply involved with the animation from the scriptwriting stage.
As it had been a while, there was a lot Iíd forgotten, but as expected of the creator of the original work, I was soon able to get back into the tempo of things, at least.
For this film, while leaving the atmosphere of the original intact, weíve added just a little bit of modern flavor, so I think it will be an enjoyable piece of entertainment, just like old times."
Set to release on March 30th, 2013. I know many others will simply not care, but I for one am completely stoked. I just hope that it won't be 100% fighting like Z was.
Oh yeah. Source.
