I feel "personal reasons" might just be a cover if they are far out of Harvey's path. It might actually be Toei, seeing how they apparently offended them by joking about the "real life C&D." Which would suck; I wouldn't've given a single shit about a DBZ revival if DBZA didn't have me caring about the series again.
At least Madhouse seems to like them, between Hellsing continuing and TFS is doing an actual dub, like holy shit. Hopefully they'll finally be onto bigger & better things, at least. But I still hope we can at least finish the Cell Games. I never cared much for the Buu Saga, anyway.
