In any case, the new saga will have to ignore the fact DBGT has EVER existed in the first place for the story to be good or make sense.
This is
not helped by the fact that a HUGE portion of DB
Z games that has kept the franchise alive for the last 10 years has DB
GT charaters in them and has a substantial fanbase, which WILL lead to certain fans whining "what happened to the GT storyline!!"
