I'm debating whether to preorder/first day purchase like I did for Oblivion, or wait until xmas since there would probably be lots of good mods to make the game better for PC (especially if they keep that consolish inventory UI for the PC version)
By Christmas, my current projects might have moved on to another important (= streesful) phase, so I'll probably take as much free time as I can in november

BTW, I just found that "they" have already opened the Skyrim Nexus. Read in an interview there that the scripting language of the engine has been overhauled to allow for both more funcionality and coherence in syntax, which means that we might not even need things as the Script Extender for this game, which is great because of Steam's copy protection. Also, I've got the feeling that the usual suspects of the Elder Scrolls / Fallout modding scene are already preparing their tools (such as Mod Mangers etc).
With the improved scripting language, I might even try modding again.
