Now I'm fairly certain PC will get it a month later. Here is the simple why:

The game files refer to it inside the datafiles with the coding DLC2_###data###. That makes it official it seems that this is the second DLC and whatever Hearthfire is considered as, was not counted as the XBOX deal.

That makes one wonder if there'll be more DLC's after this one, or if from now on any further DLC's depend on how popular Skyrim remains. The first 2 DLC's were more or less obligated to Microsoft.
