No! Technological advances = bad! Very very bad! I′ve explained it before and I bet I can give you a thousand words report on why it is bad. But for now I′m tired and sleepy. Just look at Fable and how greatly it worked out for that series to allow you to have guns that ended up being so overpowered you hardly ever needed to touch a sword again, ever. Much less a bow...
To respond and reiterate my previous point, as long as all tech is within the realm of the lore, I would be very happy to see "technological advances". Keep in mind 2 things in relation to this, however.
1. It is 200 years in the future from Oblivion. A lot of advances could have been made.
2. Alternately, Todd himself has stated that Skyrim will be more "barbaric", rustic, and almost backwards technologically compared to the "Renaissance festival" style of Cyrodiil in Oblivion.
Therefore, I would expect no advances in tech as a general rule for the whole of Skyrim, however, that doesn't rule out advances of a foreign nature from other lands, races, and/or other eras entirely.....
