No none of that is happening.... the only reason dbe was made was to secure the rights.. that's it.there's not going to be a reboot...chances are they'll make a sequel
Something else that I think should change and hardcore fans might not like it, is the symbols on people clothes from Japanese to something understandable like the Capsule Corp or Red Ribbon emblem. Hardcore fans might know what they mean but what about people who have never seen the show. Did anyone who watched DB:E but never the show know what was written on Goku's orange uniform?
If they get Akira on board again for a reboot maybe get him to redesign the Japanese symbols in the vain of the Capsule Corp and Red Ribbon Army ones. Maybe that way hardcore fans would be interested instead of angry at the change.
