One thing that really bugged me with Oblivion was that you couldn't toss yoyr gold on a table/floor/anywhere like you could in morrowind, so I really hope that's an option again in skyrim.
I just love building forts out of money in the middle of nowhere.. then making it go BOOOM... I also hope that squirels are in game as well. So I can make them rich beyond their fuzzy little dreams, by raining showers of gold coins down apon them.
