The reason for all of this is the fact that bethesda has released very little information about the game. This has led many to simply hypothesize on ways they will change things in Oblivion. I ask you to think about it in a different way, there will be many new thing about this game that are going to astound you, we just have no idea what they are yet.
The best thing to do and the thing that excites me the most is thinking about how much Oblivion changed from Morrowind (yes, in some bad ways) and apply that to the change from Oblivion to Skyrim. We have no idea what this game will be. Personally I think bethesda will be able to improve more off Oblivion, which was much harder to do when going from Morrowind to oblivion.
Please dont flame me, I am just giving an outsiders view of this forum. Hopefully it will be refreshing.
