What if something big is going to happen that we are not ready for?

What if Durin appears in patch 6. X, and then Signora arrives in the next patch? Durin and Signora do something* something* that leads to the Capitano's birth in the following patch after Signora's appearance.
That will undoubtedly be the best region for getting these three characters.

And, also Lore-wise, it all makes sense for these characters to come in consecutive patches.
Up to now, all the leaked points point to this theory. What do you think, comrades?
