That's a question that popped up in my mind, just by witnessing the amount of material & hype we're getting from official sources!
I think we hadn't that much stuff so far, neither in the Future Trunks Arc (As far as i can remember, there was only one poster with Black, Trunks & Mai with a shotgun).
Also, we'll have a brand new Opening, so a huge amount of work was put by Toei just on that stuff.
So far, Dragon Ball Super sagas lenght were:
Battle of the Gods Arc:14
Resurrection F Arc: 12
Champa Arc: 13
Future Trunks Arc: 20
Universe Survival Arc: ?
How many episodes do you expect, and how many of them would you like?
I think i would be bored for a 40 episodes tournament only stuff, hopefully we'll get some decent amount of battles, before something evil happens with bigger implications!
