iPod Touch and Nano blueprints revealed?

iLounge has uncovered possible blueprints for the next-generation Apple iPod Touch and iPod Nano.

Design blueprint for 2G iPod Touch

Sources at iLounge have unearthed two compelling design blueprints for Apple's next generation of iPods. While dimensions and blurry photos of the 4G iPod Nano redesign have been floating around for a few weeks, this is the first alleged iPod Touch redesign we've seen.

The supposed blueprints, often offered to third-party accessory manufacturers prior to an iPod release, don't reveal much in the way of shocking new details. If the specs are correct, we'll see tapered edges and rounded backs on both the 4G iPod Nano and 2G iPod Touch, as well as a badly needed volume rocker switch on the Touch. Dimensions also point out slight millimeter increases in the length and thickness of the Touch, and one of the skinniest Nanos to date (6.08mm thick).

We'll see how well these blueprints bear out next Tuesday. If these modest redesigns are correct, I suspect next week's biggest news will be improvements to Apple's iTunes software and steep reductions to the price of the iPod Touch.
