So, we realistically have at most like two more months after that of canon episodes, depending on whether or not any of the recent light novels get animated. The animators will almost certainly look to animating the novels and any other material. They'll need to create a lot of original content in general to fill up the gap of the Blank Period as well ;)

As for the fight, I'd say that it'll probably be a month or just over a month, as the animation teams will almost certainly want to expand the battles to make them more majestic and realistic compared to that of what was shown in the manga.
