We are learning that AT&T will be the only game in town (carrier wise) for the Windows Phone 7 U.S. launch. The Wall Street Journal reports that AT&T will kick things off by announcing three Windows Phone 7 devices on October 11, 2010 and having them on the shelf on November 8, 2010. Confidence remains high that the HTC Mondrian, Samsung Cetus and LG Optimus 7 will be those three.

Not exactly ground breaking news but it is just one more confirmation of time table Windows Phone 7 is on. Our guess is that T-Mobile will get into the mix later this year and all indications still have CDMA phones surfacing some time next year.

This will put AT&T in an interesting situation. They have the iPhone, a strong Blackberry and Android presence, as well as a few Nokia and Palm phones in their smartphone line-up.  If our math is correct, when you add in the exclusive period to offer Windows Phone 7 AT&T will be the only U.S. carrier to offer all the smartphone systems under one roof.

It will be interesting to see how Windows Phone 7 will match up against the other systems but could AT&T's stacked deck hurt initial sales of Windows Phone 7?
