Well, the precedent is that Dragon Ball Super follows the same arcs as each other, as it's supposed to be the same story, and it is likely that they're going to continue with that trend. I wouldn't be surprised if it ended up that they decided to wait just so that they could have material to not catch up quite as fast. At absolute most, they might cover Broly in an arc again to pad out time to allow the manga to get farther, assuming the anime comes back within the next year or two, which it likely won't.
And if we'd not get anything more due to them not wanting to spend the extra money, then I promise you that original arc would be garbage as well because it's not like they'd just give more money to whatever original arc they would produce than they would to a story arc that's already had the plot points written out for them to work with.
