TES games have always been first person focused. They have mentioned serveral times that they are making improvements to the third person view.
The game is focused on first person as it always has. That being said, the team has put a huge emphasis on making it look great in 3rd person. For those of you that played Oblivion in 3rd person, I can't imagine you not being pleased with the improvements that have been made.
In case you missed it, here's what Todd discussed in a recent IGN interview
IGN: Regarding the first and third-person views, are both included in Skyrim? If so, are both being designed as equally viable ways to play?
Todd Howard: Yes, we have both. 3rd person, with the new animation system, is better than ever, and people really seem to enjoy playing in it, seeing their character. But it's primarily designed as a first person game. I see the 3rd person as an extra, and certain things like picking up objects, talking to people, whatever, are always harder in 3rd person. Some people on the team think the combat is better in 3rd person because they can see their surroundings better. Personally, I usually play 1st person unless I'm just running through the wilderness and want a different view.
