As Apple sets the stage for unveiling the much-awaited sixth-generation iPhone at the Sept. 12 event, rumors from various sources claim that the Cupertino tech giant may also release two or more revamped iPod lines in multiple colors, different sizes, and varying storage capacity.

According to 9to5Mac, "details on the changes coming in these new iPods are currently scarce." However, 9to5Mac believes that "there will be at least two new/updated iPod lines and possibly a third."

In July, an increasing number of reports indicated Apple was planning to provide a significant makeover to iPods by the end of this year. MacRumors reported that KGI Securities analyst Ming-Chi Kuo, known for his previous accurate predictions on Apple's product release plan, released a new report detailing Apple's upcoming release plans. The plans clearly stated that the company has a very busy September-October release schedule.

The release spree, the report opined was slated to begin with the "all-new" iPod touch and iPod nano models. While details on the specifications of the device were not provided in the report, it suggested that like the next-generation iPhone, the revamped iPod model would also feature in-cell touch panel technology.

Currently, rumors surrounding an overhauled iPod line-up have resurfaced. iJailbreak, in its Sept. 4 report, claimed that the first iPod in Apple's line-up to receive a makeover is the iPod Nano. Per iJailbreak, the iPod Nano will now have Wi-Fi connectivity and increased storage space. The second iPod slated for a revamp is the iPod Shuffle. Folks at the iJailbreak believe that the Apple will maintain its current form factor but will increase storage options.

However, the tech Web site was unable to confirm whether Apple is planning to release a completely brand new iPod with a larger display, home button, and Wi-Fi connectivity at the forthcoming press event.
