Windows Phone 7 Launch Date? Oct. 11, Oct. 15, or Nov. 11?

Microsoft has been saying that Windows Phone 7 will be available “for the holidays”. However, they’ve never specified which holiday. Labor Day has passed. So, we can eliminate that one. In early August, Microsoft’s COO was reported as saying that Europe would see WP7 phones in October while the U.S. would get it in November. A few weeks later, I noted that the first WP7 books were set to ship on November 15 supporting the earlier report in my mind.
