Ok, instead of removing the DragonBall Reboot listing (as Kazuaki Kiriya requested), IMDB decided to add more details to it. It is now claimed that this film will have an estimated budget of $100,000,000. Given that we already know this listing is fake, I would not take this new information into account. And seeing how Dragonball Evolution only had a budget that is 1/3 of that, it is clearly obvious if a DragonBall reboot was created they would not have high enough expectations to fund that much money.
It was reported sometime back that this listing is most likely a fake since Kazuaki Kiriya (supposed screenwriter) denied any involvement in this movie.
