There's no reason why dragons wouldn't migrate to Solstheim, especially given that the Dragonborn and Paarthurnax are in Skyrim, and it isn't necessarily true that the player will be able to freely mount dragons like horses. Maybe the Dovahkiin will fly on Odahviing to get to Solstheim.

I doubt that Bethesda would be creating a false DLC to disappoint fans. The reason why they'd leave code would either be to get it leaked deliberately or to reduce file size in the DLC by putting code in the small upcoming patches.

I also don't see what your point is in not putting dragon animations in the patch.
