Media related is still speculation, I think the iPod line is ripe for a refresh, or the long awaited iPhone Nano will be released, or maybe even a convergant OS that mixes iOS with OSX, beating Windows 8 to the punch for a single OS on all platforms.
If it is another boring incremental upgrade or a new product that has stolen the name of an existing product again it will be very disappointing, Apple has plenty of promising thing they could do, don't let us all down, again.
