Sales reports on the iPods, iPhone, and Macs. Update on where Leopard is and when it is (still) expected.
Mac mini - It will get a major update, a redesign, or discontinued. Come Paris, it will be a year since its last update.
new hardware - If the Mac mini is discontinued, especially if the 17" iMac is also discontinued, then we could see a headless Mac. Since gaming is coming back to the Mac the "main" feature will be a user replaceable graphics card.
iWork - I think we will see a demonstration of the updated, and new, apps in the suite. A spreadsheet is a no-brainer but I am hoping for a database, one that is relational and not flat-file.
iPods - Full screen iPods. The shuffle gets 2GB and the nano bumps the 2/4/8GB models to 4/6/10GB and the prices stay the same.
iLife - Steve will want to save this for MWSF.
