The new iPods will run a derivative of the Mac OS-based iPod software introduced as part of the iPhone in June, according to AppleInsider.
Wired's Gadget Lab blog is calling one model the "Fatboy Nano:" The Fatboy Nano will play video and come in matte black, silver, cranberry, light blue, and light green. We guess that there will be 4GB and 8GB models, but with the bulk discounts Apple must be getting on all that flash memory it's buying, a cheapish 16 gigger isn't out of the question.
The new iPods will look much like the iPhone, with some differences: the outside rim is black, not silver, and more flush with the screen, no ear speaker or microphone for phoning, and slightly thicker than the iPhone, according to 9to5mac.
At least a couple of the new models will retain the click-wheel interface of the existing iPods, AppleInsider said. They'll integrate with iLife '08, including updated ways of displaying album art, a Leopard-style interface, world clock widget similar to the iPhone, and "a new photo feature that would allow iPod nano users to browse their iLife '08 photo 'Events' via a CoverFlow interface controlled by a physical click-wheel," AppleInsider said.
