My own crazy predictions:
-Shuffle price going down to $49
-iPod nano remains in the same form factor, with updated interface, new features (themes & backgrounds?) Maybe the click-wheel will light up like in the ads? Price drops: 2GB $99, 4GB $149 and 8GB for $199
-The current full-size iPod becomes what the "Fat nano" pictures were showing and goes all flash. Same updated interface and features as the new nano, supports current iPod games. 16 GB $249, 32GB $299.
-iPod Touch, wide-screen touch-screen HDD iPod. Runs OS X, has cover-flow , some apps and new games (these will also run on the iPhone). 60GB $349, 100GB for $429. Wifi, Safari and YouTube may or may not be included, but in any case, Bluetooth will be present. I'm not sure about the price, HDD capacities and the Wifi aspect, mainly because of the "iPhone cannibalization" problem.
-Wireless Bluetooth remote. Since it's hard to operate a touch-screen music player without looking (lack of tactile feedback), a new Bluetooth wireless remote is introduced for the iPod touch, but will also work with the iPhone. Shaped like a shuffle, but with a distinctive mark (black case?), you can plug any headphone you want and control your touch screen iPod or iPhone without having to look at the screen.
-Beatles announcement.
-TV shows and movies announcements, new countries? Europe and Canada?
-Some Apple TV stuff to try to get this thing off the ground.
