DAPreview.net reports on what initially seems to be an incidental finding... in which Apple changed the name of the iPod Photo User Guide PDF from "iPod_photoUserGuide" to "iPod_with_color_display_User's_Guide".
This distinction is not a new naming convention and is listed in Apple's "Identifying Different iPod Models" support document as an alternative name for the iPod Photo - "also known as iPod with color display".
However, we have indeed heard reports that Apple's iPod line will advance in the future, phasing out the iPod Photo designation by trickling down color displays in the core lineup of iPods. Also reported has been rumors that Bluetooth and Rendezvous (now Bonjour) enabled iPods have been making the testing rounds.
Bluetooth enabled iPods have been hinted at for some time now.
