Yeah I saw that now, youtubers are saying it prob means like you said super will end but another dragon ball series will start like z then gt then super and now something else which would make sense especially if the movie at the end of the year does extremely well.
Yh you would expect it to return, the franchise is a powerhouse and Super has been extremely popular, there's also so much story potential left. We also have to see what the manga does, if that passes the anime ending then the anime will hopefully return. Either way it's looking like the anime won't ve on for atleast a year.
There's a fan theory at the moment that ties the ending of Super with the new movie we're getting later in the year.
So basically he has predicted the ending of super and thinks that Goku will wish for all the universes Zeno erased to return. This is where there will be a problem. We know that Zeno previously erased some universes already years ago, so Gokus wish will unintentionally bring these back. He also believes that the universes were also triplets and not twin universes like they are today, so that means there will be another race of Saiyans.
Now according to leaks, the new movie is apparently going to be about the Saiyans origin and the SSJG (some **** named Yamoshi or some shit) we heard about when Goku first did the transformation when Beerus attacked. The movie could potentially invlove the Saiyans from this 3rd universe.
