Just for fun then - no flaming if I'm way off please!!

Mac Pro Case redesign
New Monitors with camera, slim with styling a la iMac
All Mac's to gain a HDMI port.
32GB iPod Touch, phasing out of 8gb
16gb 3G iPhone + SDK details
Spec update of Mac Mini to differentiate more from AppleTV, plus coloured versions along the lines of the iPod Shuffles. (Sony are doing a mini-sized VAIO HTPC which has some pretty good specs)
Leopard update.
Blu-Ray as an option across the entire Mac range, announced as Mr Jobs gives Mr Gates the finger... although I suspect any HD announcements may be held back until the whole Warner Brothers thing has settled.
Apple to announce a deal with Sony regarding streaming content from Mac's to PS3, possibility of PS3 running iTunes - you can already access iTunes store from PS3 so why not be able to purchase from it. Overall I think there will be a focus on interactivity with other devices - I think many people in the Windows world see Apple products as keeping themselves to themselves.
