I hope Oblivion doesn't conflict with Supreme Commander. I'm planning to buy SupCom at release, and Oblivion once the first expansion pack (==major bugfix update) and good mods come out... but I don't know the timing of either event. I'll probably have a nice, new computer by then.
From the mod side, I'd like to see a much better experience system, vastly less ugly people, spears, crossbows, short/long blade split, and from what I'm hearing, a redo of their leveled-list system, and a "PC Version" mod that de-consolizes the interface. Morrowind was much better after various mods came out, and this game repeats some of the same failings... so maybe the same people will fix them
