Ok, assuming the 2.6's get announced tomorrow, i believe WWDC will have the following
1.)iMac G5 15"-20"- 1.6-2.0 Ghz single G5's with FSB at 33% of the proc. speed (Apple loves to cripple the iMac

), 120 GB HD, 256-512 MB RAM, ATI Radeon 9600 and COMPLETE redesign for the G5. Heat in the current form factor would be a problem so i expect this to be a major portion of the announcement.
These specs are based purely on if they intend to keep the iMac in the current price bracket. These would be VERY competitive IMO to similar PCs (or at least a big improvement over the current iMacs).
2.) Tiger - Steve Jobs demos 10.4
3.) Displays - new design, new models, etc. etc. etc.
4.) iPod - models are 20, 40, 60 GB. i'm hoping the fabled features of color video/picture capabilities will come up, but i'm not expecting anything.
5.) Any other updates for iLife, SDK's, and other developer stuff
6.) ??
but of course, as all of you will soon point out, i know absolutely nothing ....
