The recent supposed screenwriter for the Dragon Ball movie reboot has been officially taken off the crew list for this film. What’s not surprising is the fact that every other detail remains in tact. IMDB has their heart set that this film will happen and has been announced. Kazuaki Kiriya did in fact inform IMDB that his involvement in the supposed reboot was not true, however they stick to their story that this movie will occur (which are only rumors, since a reboot has not been officially announced, nor has the sequel).
If there was a planned reboot, IMDB would be the last official source to take credit for it. Whoever is approving the recent contributions (to both Dragonball Reborn and Dragonball Reboot) needs to seriously reconsider their facts and keep it all as rumor, since that is all it has ever been since Dragonball Evolution released.
