The musical theme has given rise to widespread speculation that Apple will use the Sept. 1 confab to launch a new version of the iPod Touch. Analysts believe it will feature dual cameras—one rear facing and one that's forward facing. A front-facing camera would allow buyers to use Apple's FaceTime video conferencing app on the device.
The new iPod Touch also could include greater storage capacity. The most available currently for iPod Touch is 64GB, on the model that sells for $399.
Although the iPod dominates the MP3 music player market, sales have tapered off of late. Unit sales slid 7.7% year-over-year, to 9.41 million, in the second quarter, according to Apple. The company is hoping the introduction of a new model will reinvigorate the franchise, which has taken a backseat to buzzworthy products like the iPad and iPhone 4.
Some analysts also speculate that Apple will also introduce a beefed up television console.
The company is rumored to be in talks with major networks with an eye to offering TV episode rentals through a service that would be called iTV. Apple's current settop service, Apple TV, has largely failed to catch on with consumers.
