Earlier today, we reported that claims from a Kaufman Bros. analyst were released, where he states Apple will be releasing a new iPod nano with a smaller form factor.

Now, iLounge is pointing to a Chinese website that is showing off cases that are apparently designed for Apple's next-generation iPod nano and iPod touch. The case comes from case manufacturer X-Doria.

The iPod nano cases show a more squared off design as oppose to the current tapered edges design. Due to the fact of a more squared off design, it is possible that the next-generation iPod nano will no longer sport a widescreen, but will include a square, touch-enabled display.

The nano 6G case features an open strip on the rear - perhaps for a camera or built-in clip - as well as what appear to be volume buttons and a larger button on the top side while a Dock Connector and headphone port are along the bottom.

If this leak turns out to be the final design of the next-generation iPod nano, it would bring it much closer to the iPod shuffle, whose future is unknown at this time.

The next-generation iPod touch cases show a camera hole on the rear of the device, including flash. It was rumored earlier this year that the iPod touch would be gaining a rear-facing camera, but recent rumors are claiming that it will be a front-facing camera instead. The iPod touch cases do not include a front cover for the device, so there is no evidence whether there will be a front-facing camera or not.

Apple is holding a media event on September 1st where they are expected to announce a new iPod touch and iPod nano. You can read all of our predictions here.
