As hinted at earlier, it has been confirmed that we will see a second generation iPod Nano at Apple's Worldwide Developers Conference this August. In addition to a metal housing, the Nano is expected to come in more colors than just white and black. It seems that Apple is going the way of the successful iPod Mini. The new Nanos could also sport a higher-end model featuring 6 or 8GB of solid-state flash memory. Hopefully, Apple doesn't have to change the form factor too much to fit in all those RAM chips.
