This is my theory:

Before 4x12, Regina will found out who the author is: The Sorcerer, and he will show up on Storybrook.

When Rumple founds out that he is actually the author of the book, he will try to defeat him to rewrite the book himself. But the Sorcerer is too powerful for Rumple alone, so he is making the "villains army", so all together will defeat him and get their happy endings.

I think the villains will kill Robin Hood to get Regina in their side, because if they defeat the Sorcerer, Regina can rewrite her story and bring Robin back to life. (Similar to what we saw with the Knave/Red Queen in the finale of OUaTW)

Maybe, even Rumple will control Hook to get him in their side.

IMO, the Author and the Sorcerer are one and the same. I highly doubt they will introduce 2 different all-powerfull characters in the same season).

So, maybe the season 4B will be the Villains vs The Sorcerer (and probably we are going to see one villain backstory every week).

In the season 4 finale, the villains will defeat the Sorcerer and will take over the book and erase all. And that is going to be the cliffhanger in the finale. In season 5 we will see all the fairytales destroyed, and the villains being thriumphant

(If this is last season that could even be a great series finale).

In season 5 we will see all the fairytales destroyed, and the villains winning. One fairytale every week, just like Season 1.
