there have been a lot of theories already since the finale aired and most of them seem like they're grasping at straws, however! there is one that somewhat makes sense, the theory is that during the eenie meenie miney mo scene, there are a some 1st person shots before the whacking, to which they're saying that the one who dies is getting all of the first person moments. (sounds reasonable)
if you go back over the whole course of the episode, they are also theorizing that the first person shots inside the van also belong to the soon to be dead survivor.
the only thing that makes me not follow it completely is "who" they said those first person shots belonged to.
if you look at the shot inside the van just as the doors open, you can see that the person is standing/kneeling to the left of the camera with a small bobbing of a head in front of them (BJ jokes aside now
) cut back to when we see who is inside, you can see that michonne is to the left (or right as we see it) of the van.
so what this theory is saying now is that it is Michonne that will most likely get batted.
normally i wouldn't post a theory, but other than the "result" being Michonne (which i don't believe) the rest of it does seem plausible.
here's the link to the theory if anyone is interested:
