Skyrim - Interview @ Xbox360Achievements

Bruce Nesmith, Lead Designer, for this game did an interview with Xbox 360 Achievements.
They talk about how animals will wander the world:

When we first sat down to make the lists of creatures and encounters, we organised everything by ecologies. Every creature fits into a set of creatures so that the group makes sense as a whole. You won’t find random mixtures of monsters in a dungeon, or wandering the frozen steppes. They have defined predator/prey and ally/enemy relationships. So we have giants that keep herds of mammoths -- if you don’t disturb them, they won’t bother you. We have wolves that hunt deer. We have undead draugr that climb out of coffins to attack those that disturb their rest.

They continue to talk about the eapons, the items, the combat, and much much more.
Here's what he had to say about combat melee skills:

Melee weapon skills are now distinguished by the single most important attribute they have. Can you use it with one hand, or does it take two? The differences between Blade and Blunt in Oblivion were minor. You didn’t really have a reason to choose one over the other. In Skyrim, the choice is between using a weapon and shield, or a really big two-handed weapon and no shield. The differences between swords, axes and maces comes out in the perks you choose. So you will still have a reason to choose axes over swords.
