Except Future Trunks sorta kinda killed the Androids. Even if the Majin Buu saga happened, it would have been way different. For one, Super Saiyan 2 would have been discovered a lot later if at all.

Basically, there's no reason for some huge Future timeline. Besides, everyone but Future Trunks and Future Bulma is alive, aside from some insignificant characters like Puar (when it comes to fighting).
