Also, I'm fairly certain this Oblivion update has very little new geometry - I think it's all in the same locations. So they just added new quests. 40 hours of quests are much easier to get than 40 hours of running and shooting.
My problem with these delays comes exclusively from it being episodic. With normal games you get some kind of resolution (yes, even with HL2.) There's a beginning, middle and end.
With these episodes we got a beginning. Which I now forget. And don't much care about. So the delay just makes me remember less and care less.
But that's a flaw of episodes.
