So judging by the english episode titles I see on the dragoball wikia, I see that Goku becomes a God in episode 9, or possibly 10. So basically the first 10 episodes of the 100 eps DBS = BoG and then dealt with. That's pretty quick to be fair. I guess we'll be seeing how Vegeta becomes a ssjgod after that somewhere.
Where of those 90s eps do you think RoF's events are? In 10-20, 20-30? At about halfway in DBS?
Also, I don't think they've retconned BoG in any major way, so I assume Gohan being reduced in power and relevancy as a fighter continues, as in RoF he explicitly says he can only go ssj. If Ultimate Gohan was basically the most anticlimactic dumb build up of DBZ ever, I think I'm gonna skip buying U gohan. His role is next to completely ignorable, impactless and apparently doomed.

News | "Dragon Ball Super" Complete Showcase Event Reveals Series Plot which I'd forgotten, I the space between DBS' first 10 eps dealing with BoG, will be something like 5-10 episodes, and then RoF itself will also probably be about 5-10 eps. Assuming more happens to setup that they're gonna go to universe 6. I wonder who will travel along. I wouldn't be surprised if Gohan stays behind, and goku vegeta krillin piccolo and trunks and goten sneak in against their mothers wishes. Maybe Toriyama will leave piccolo and or krillin behind, dunno. Maybe Tien, if we tien fans are lucky... I wonder what this universe 6 has in store...
