There's alot of reasons why it might turn out great, with Toriyama being heavily involved in the early stages of the writing and story. Toriyama had little to do with GT, which is why it sucked. In Dragon Ball Online, Toriyama worked on a new story that is the true continuation of Z, as GT canon is completely erased and disregarded within it. If Toriyama has the balls to wipe out GT with a continuation of Z, then it could be amazing
. Z left us with Uub(who was butchered in GT), Trunks and Goten(who were both SUPER butchered in GT) as the future of the Z Warriors, and then Gohan (the most ruined of all in GT)who had essentially surpassed Goku as the strongest warrior in the universe.
I am very excited, this series is a huge deal to my nerdy ass.
