For the sake of plot, Blackbeard and Co. Probably what will happen is Blackbeard will gather allies to his side to make up for the numbers, the Whitebeards will start to crumble with Marco not living up to Whitebeard's standard, and then a big battle where they lose and split.

If Blackbeard has not learned not stop absorbing everything and making things not drawn to him, he'll probably kill and steal Marco's powers. If he has, then Marco will live.
