Recently, a team behind Dragon Ball Super: Broly hit up the 2019 International Beijing Film Festival to promote the anime feature. It was there press asked Norihiro Hayashida about the continuation of Dragon Ball Super, and he had the following to say:
“Nothing is fixed now. Toei hasn’t [come] up with anything yet, [not even] about arrangements and when it will start,” the producer said (via Goveta XV).
“We are looking forward to it as eagerly as everyone else. There is nothing that we can answer about it right now.”

This really doesn't give us a solid yes or no but knowing Toei hasn't done anything (if this is legit) then we likely won't see anything new until 2020.
