The speculation that Steve Jobs is about to unveil the next generation of iPods - presumably with widescreen video and an Apple OS like the recently launched iPhone - gained a whole new life when the invite pictured on the right went out to the press recently.
It seems like the right time for a new product launch. Christmas is just around the corner, the current iPod is looking a little tired from a product life-cycle standpoint, and new-look iPod would help bring the design in line with the iPhone, iPod Shuffle, MacBook, and new iMac with their shining aluminum cases plus possibly provide some of the great interface innovations that Apple introduced with the iPhone.
Then again, Steve could be getting ready to let everyone know that prices of songs are being dropped from $.99 to $.90. We will just have to all wait and see.
