It looks like AT&T’s extensive Windows Phone 7 lineup reveals possibly six Microsoft devices. Engadget has obtained information that HTC and Samsung will be among the early Windows Phone 7 makers to launch devices on AT&T, to launch the Samsung Cetus, HTC Surround, and a yet unheard of Samsung Focus. Additionally, there will be three additional Windows Phone 7 devices to join the early Samsung and HTC launches on AT&T.

The carrier will also be colorizing its BlackBerry Torch smartphone offerings with a red/black color scheme, a pure white offering, and also an olive Torch.

Also spotted on the leak is an AT&T-branded Galaxy Tab, which is a 7-inch tablet that provides phone functionality.

The devices are expected to be available for the holiday shopping season. It looks like AT&T will be keeping busy the end of this year.
