Not sure if you want to add this or not but Dragon Skeletons remain on the ground even after you have absorbed their souls which can be seen and confirmed in the Demo Video.
After the first Dragon is killed and its soul is absorbed the Skeleton is there on the ground when the Ice Dragon arrives and is being fought.
This makes sense now that they confirmed the making of Dragon Armor in Heavy and Light variants.
I assume you will be able to loot the Skeletons for Bone or Scales to make the Armor.
