Like the prefix says this is a prediction and its not really based on much information.
With that being said I think Oro will stop Madara. Oro is the only other person who has a comparable amount of knowledge as Madara, in regards to the God Tree. Madara seems very confidant in his ability to switch spots with Obito and im guessing he knows Obitos weakness all to well. So maybe Oro will be able to stop Madara from exploiting them. Oro should also know any type of weakness Madara has because he know has all of Kabutos knowlege.
The manga has also been giving Oro a decent amount of screen time and his facial expressions seems as though he may have a change of heart. It just seems to me like he will do something of some significance
Although with the kage coming just about anything could happen.
