Apple has historically used a September event to introduce new iPods and announce enhancements to the iTunes service. Apple TV, which is widely expected to be refreshed and relaunched (possibly with a naming/branding change to iTV), was originally introduced at a Fall event.
In addition to the anticipated Apple TV update, many analysts are predicting a 4th generation iPod touch (possibly with cameras), an iPad refresh, an iTunes update (likely to 9.3 or 10.0), and a TV episode rental scheme.
Regardless of what Apple introduces, TUAW will be virtually there to meta-liveblog the event, bringing you updates and analysis as they happen.
