Yeah if it's like GT i will write an angry letter lol but seriously i think it could work just he would have to make sure the right people die in this war (if any at all) otherwise like someone said in an above post, we'd see the same thing we have already seen, but the reason i think it will happen is because it feels like no matter what happens in the war kishi cant kill sasuke yet (we all know it's going to happen) it just feels "too" soon imo.
Why is everyone saying if its like GT you do all know that GT was not canon. Toriyama never wrote any GT manga it was all fabricated by the anime studio to prolong Dragonball.
And technically there were 4 major time skips in Dragonball.
DB- After the King piccolo saga
DB and DBZ- between the start of the two series when Gohan was born
DBZ- After Frieza into Cell saga
DBZ- Buu saga
Remember that even though the anime has a different title it is technically the same series from Dragonball to the end of DBZ
Dragonball GT is complete nonsense that is not canon therefore not real psshhh SSJ4 what a joke. Oooh I am a red monkey man now with no trademark SSJ gold hair
