For undead I remember Sven toying around with the idea that you became undead or could become undead when you died, but that was early days of the post-kickstarter campaign so it has most likely changed.
That being said I hope/wonder about the undead character creation. Specifically if we can choose an undead X race. IE can we make an undead lizard or elf? Will we be locked into 1 race look (with standard variance of course)
On the topic of elves, it is true they aren't the typical fantasy/Tolkien elves but from what we see so far I see this as a fitting direction to take them. Having a sort of wood elves who evolved/ were created with the ability to see memories of the things it eats. (maybe only for sentient beings, although every creature appears to be sentient in D:OS) Perhaps they only eat things that died naturally or perhaps they view themselves as another part of nature and do not make the distinction.
All that being said it would make an equal amount of sense for the undead to be the ones with the corpse interaction, and we don't know they won't have one.
