I wonder how far the body editing goes. Immaturity aside, I mean what would you edit? Muscle tone maybe, but you'll usually be covered up by clothes and armor so whats the point in that? nipble size and color, bust size, finger nail length? Most things you could edit seem pointless unless you plan to play as a nudist.
Might be interesting if you can control the size of a khajiit and argonians tail or how big or jagged their claws are. Definitely hope argonians get more 'hair' choices, the 3 or 4 they had in oblivion was too few.
By that logic, you might as well say being able to edit your face is pointless since you'll just cover it with a helmet.
Besides, I don't your going to be changing those kind of details, probably what you're going to change is things like how muscular your character is, possibly body weight and how tall you are, and really, those are things that would likely be visible with clothes too, especially since, as you should be able to see from the trailer and images, Skyrim will feature some clothing and armor that shows skin, just look at what the player character wears in most images.
