US Windows Phone 7 debut on November 8th 2010?

It's looking more and more likely that Windows Phone 7 won't be arriving in the US until early November, unlike the expected October debut in Europe.  After speculation over the weekend that Microsoft is planning a WP7 launch party in New York City on October 11th, Paul Thurrott has chimed in with word from his own "very reliable source" that in fact the company expects to debut Windows Phone 7 in the US on November 8th 2010.

In fact, Thurrott claims, the October 11th event is unrelated to Windows Phone.  That still leaves rumors of an October 21st event in Europe which will see the new smartphone platform go on sale in the UK, France, Germany, Italy and Spain.
