Adding even more to the tactical element in combat, as well as overall character individuality and individual play style, would be the inclusion of staves as physical weapons, not only as ranged spell casting tools. Even though this is a very specific area, I think it should receive attention because the staff is perhaps the most iconic weapon for certain classes/play styles. For example, as a spell casting weapon it 'represents' wizzards/mages/magic users in general (this is how staves functioned in Oblivion), but as a regular physical weapon it 'represents' the traveller/pilgrim/bard (this was how they functioned in Morrowind).
Therefore if staves will be available to use as spell casting tools (which we saw in the trailer), I think it would be perfectly logical and fair for players leaning towards the traveller/pilgrim/bard tpye of gameplay to have the option of a staff as a physical weapon (1- or 2-handed, I don't mind), that you would use to strike at enemies. After all it's the most iconic and representitive item for that kind of character.
Whether this is implemented or not, an excellent touch would be instead of keeping the staff 'sheathed' the whole time like other weapons (in Oblivion you kept it on your back), the character could walk around holding his/her staff in one hand the whole time, much like a deceptively harmless walking stick. When 'unsheathing', they would simply ready it in an attentive stance. Even this I think would address my concern of visually defining and representing the traveller/pilgrim/bard type of character.
This, belive it or not, would probably be my biggest concern for Skyrim and the thing I would want to see most lol. What to do you guys think? Hope this idea receives support.
