There is no real unique shape to Skyrim, it has a very boring shape, the only province with a larger lack of geographic uniqueness is Elsweyr. It's the shape of a brick. All the other provinces of Tamriel have gorgeous geography, High Rock, Morrowind, Summerset, Hammerfell. What I'm trying to get across is, is Skyrim's geography going to be fun, like with Cyrodil it was very unique and the river that ran straight through was a nice sense of location, will Skyrim have that? I would've loved Bethesda to visit say Summerset, or High rock, something with a real bam factor.
EDIT: since my choice of words are causing such a startle, I would like to propose this, if the Bethesda team put the same amount of effort as they did in Skyrim to Cyrodiil, Cyrodiil would surely kick the ass out of Skyrim, but thats not the point I'm talking shape of land and how the Bethesda team could manipulate it.
