SPOILER! What are the odds we get an anime original ending?

So I doubt I'm the only one who read the last "arc" of the manga and thought it was rushed, nonsensical, and overall disappointing. From my understanding it seems to be, like most bad manga endings, the result of higher ups deciding it wasn't making enough money and forcing it to end early. But the anime seemingly doesn't have to worry about that, at least beyond having a limited number of episodes to begin with. So do you think we have any chance at seeing an original ending that fixes the originals issues?
