What about grid+list+detail, sort by, group by options and ability to change icons size's real time? Like in Windows. Customizable windows like in Morrowind(or again Windows, they can add snapping too) instead of animated transitions? Having journal separate also helps me stay away from spreadsheety.
I found Oblivion's UI beautiful and found new functionality very welcome but it wasn't optimal. I expect to see above for PC since they are making a PC specific UI.
DarnUI allowed for list or grid view, this was very nice.
