Patch 4.0 expected date?

I'd expect Cataclysm for mid-late November, in time for the Christmas sales. Which would mean the final pre-expansion patch for early-mid November. But that's just a guess.

I actually wouldn't be surprised to see the 4.0 patch the week before Blizzcon. It almost fits in with your timeline but it gives them something extra to talk about and answer Q&A about. The only thing that might push it back till after Blizzcon would be not wanting to put out a major patch at a time that a lot of devs are pre-occupied.
