This is pretty much exactly in line with the date most of us have been guessing here at WoW Insider, but let's be honest. It wasn't hard to figure out, and I'm sure all of you guys were thinking much the same thing. It'll be almost exactly one month between patch 3.0.2 and the release of Wrath of the Lich King on November 13th. It will also be after BlizzCon and not before it, so if anything goes wrong their lead devs can jump right back into work instead of needing to worry about the convention.
So start marking your calendars, ladies and gents. October 9th, WoW Insider meet at the Lost Bar. October 10th and 11th, BlizzCon. October 14th, Patch 3.0.2. November 13th, Wrath of the Lich King.
