well goku defeats the evil shenrons and when all the dragon balls are collected, shenron explains that it is goku's fault for mis use of the dragon balls and goku gets on shenrons head and leaves and says good bye to every one. then it shoews like a 2 min clip of pan as a grandma of Goku Jr fighting Vegeta Jr they both go super siayan and it ends goku leaving the tournament.....
well if you watch it and focus closely you see hints that their can be a new series or their wont be:
Reasons Why:
-it says goku will be here to defend the earth no matter what
-the end leaves u hanging
Reasons of no new series:
-You see goku saying good bye for good
-It hints that goku jr and vegeta jr will wind up being like the originals. becuase vegeta jr insults goku jr like the originals did saying he had ugly cloths and is a bad fighter as if Vegeta would call goku a low class siayan
-Most of the characters are dead.Vegeta,Gohan,Goten,Trunks yada yada yada goku(unknown)
i really cant tell what is going to happen, id like to see another series
