According to an email sent out tonight to users of MSN Direct Spot watches, which will not support the new Wave 3 version, Windows Live Messenger is set to be released on February 10, “2008” (sic).  The email gives the correct start date for the beta (Sept 17, 2008).  Of course it remains to be seen whether or not the release schedule is met, but this gives us some indication of the timetable for Wave 3 final releases.

Thanks to numerous tipsters, and a hat tip to Jonathon Kay for posting on this, as well.
