Is this the Treo 850 or the Treo Pro -- or both? Some members of the WMExperts forums found some official looking photos on a Palm domain. Interestingly, the photos are now missing from the Palm domain.

You can see in the photo that the keyboard looks small, like the Centro keyboard. Could this be a Centro-sized Windows Mobile device that is smaller than the Treo 800w? Our guess is that the Treo 850 will be a GSM version of the 800w while the Treo Pro will be a smaller Windows Mobile device. We'll see.
