UPDATE: Toei Denies Rumors. RUMOR: Dragon Ball Super Returns July 2019.

[PAOerfulone]

Dragon Ball Super returning - Yes!

Naohiro Shintani will oversee its character animations - YES!

If I had to guess, they'll most likely start like they did with Super's original run and adapt the Broly movie into anime format. Either that, or the Galactic Patrol arc from the manga.
I just hope that eventually they take that bold step and do a time skip AFTER the end of Z, because that's the biggest thing holding Super back at this point, is the fact that it all takes place before the end of Z.
GT be damned because, let's be honest, outside of Super Saiyan 4, GT kinda sucked. They could always make the excuse that GT is an alternate universe where Beerus never wakes up or they never meet.
