im curious as to how these 'new' captains will come to the scene. will they be recently appointed to their positions or will they hold some sort of tenure?

Like what David said, assuming Juki brought them in.....They're just place-holders really, nothing permanent.
Though it's more than likely they've been in their position for a while, not just now being assigned them.
