No Ipod updates (thats my prediction). apple will release new Video Ipods in the Iphone configuration before this Xmas or at Macworld next January (the extra time will allow them to add significantly more storage with flash memory to the Ipods and expand the battery life).
The Imacs will get updated, and I predict that both Imacs and Ibooks will go to Santa Rosa (the Imacs will get the 8600s, expect to see 1 terabyte hardrives offered in all the apple desktops).
If there are going to be new keyboards, then it wouldnt suprise me if we saw new Cinema Displays that are LED backlit (expect the Imacs and Ibooks to go LED as well).
