but there's also a new companion pet to go with it, the Dread Hatchling:

This even more cements the theory that these are intended to be the Collector's Edition rewards for WoD.
What's also interesting, however, is that this minipet matches the old Raven Lord more closely in style than it does the new mount. Then I noticed this new spell in the database:

It seems to be triggered by the original Raven Lord, and sounds like it might cause some sort of cosmetic love effect (maybe a few hearts?) between mount and minipet. At least that's what I'm guessing so far. It makes sense for the pet to have a link to the old mount, since it's unlikely to be able to fly and follow the new one.
