Bethesda has around 5 years to code Skyrim for all consoles...5 years. That's about 1300 week (or work) days. That is a long time to code, along with the fact that stuff like music and advertising were handled by different parts of the company.

So, I don't think the whole "Hard to code" argument is valid in this situation. If Skyrim was made and shipped in a year or two, definatley, but they had 5 years to make it...I'm also positive the Dev video for Skyrim said they started working on TES5 straight after the release of Oblivion.
