The Apple Store has slipped the shipping time for the 40 GB version of the Apple TV from within 24 hours (the norm) to 1-2 weeks. Historically, slippage of shipping times means there’s either a shortage of parts or a product refresh in the pipeline.

If Apple is going to update the Apple TV (and it’s about time it did), the September press event is a logical time to do it. September is Apple’s favorite month for making most of its consumer entertainment-related product announcements.
Of course, not all signs point to an Apple TV update. The 160 GB version of the Apple TV still shows a 24-hour shipping window. Perhaps those 40 GB hard drives are just getting harder to come by.
