In a recent interview Tod said that the giants have camps and actually live in the environment instead of just being randomly spawned like every other creature. He also said that there are other creatures (which he will talk about more in the future) that have gotten more attention also and they will live in the environment in a similar way. What do you think the creatures that he is talking about could be? Maybe werewolves, vampires, or even goblins? What are your thoughts?

Goblins were pretty intelligent in Oblivion (tribal structure, villages, hierarchy), so I think they could be a safe bet this time around, if they are known to be in the game. Whether intentionally or not, ogres, trolls, and Minotaurs in Oblivion came across as hinting at some intelligent thought, in my opinion.

I didn't even think of that haha that would be interesting too. I would just really like to see some werewolves and maybe even become one.

If he was referring to Werebeast then I would assume in that case they live like ordinary NPC's and manage to slip out of sight during the moons ascent. Unless they are crazy living in a cave somewhere. Vampires probably live in caves, in this case ice caves or sewers close to their prey with their own unique habit of feeding. It has already been confirmed that wolves and presumably other creatures have their own agendas and even small caves to live in. I do not think that standard Goblins will be present but I imagine Rieklings or Ice Goblins live in little igloos in the colder baren parts of Skyrim.
