There are two problems I have with the new information:
1) Same size as Oblivion:
A) Oblivion felt really cramped up. Dungeons everywhere, and you could run through the entire map within 10-15 minutes.
B] You could also almost see the whole map from a single spot. With Skyrim having even bigger draw distance, you'd most likely see everywhere from a single spot.
C) Furthermore, there could be no real, massive landscape. No huge mountains would fit within that area of about 41 square kilometers. "Thanks" to this, we won't be able to experience landscapes like http://www.cpawsbc.org/files/athead_Valley_from_Global_TV_helicopter_ride.jpg or http://www.ozoneeleven.com/wp-content/uploads/2010/08/Mountain_Valley_1600-x-1200.jpg

2) 130 dungeons in the game:
A) Oblivion felt really cramped up. Dungeons everywhere. You would stumble upon a dungeon almost every 30 seconds (or even less) if you ran. This made the game feel unrealistic.
B] Combined with the same size of Oblivion, though with about 70 less dungeons (Oblivion had about 200), the rarity of finding dungeons will almost be gone. Some people think having lots of dungeons is good; and so do I,
but not so it feels cramped up and like a chore that you face every 30 second.".
C) That being said; I want dungeons to be more spread out, and with 130 dungeons within about 41 square kilometers, I don't see that happening. And that makes me sad.
To avoid confusion:
Oblivion
felt REALLY cramped up due to its size of 41 square kilometers and it having about 200 dungeons.
I think Skyrim
will also feel cramped up due to its size of about 41 square kilometers (like Oblivion), and have about 130 dungeons.
It will just feel LESS cramped up, but STILL categorized as cramped up - in my opinion.
And that's what I don't like, plus with not being able to see great, huge landscapes like I linked to. And I also believe that Oblivion's feeling of dungeons becoming a chore might risk happening in Skyrim as well.
