Wow, what would that leave for MWSF? (The Pro is not going carry the whole keynote!)
More data on Steve's death (he did say the rumors were greatly exaggerated). Mac Pro's, updates on how many iTunes apps have been sold and how great the SDK is, update on the next greatest, funnest, fastest, life altering OS, updates from Intel, perhaps some wildly uncomfortable software marketing VP of a major developer that just figured out how to incorporate cover flow into their UI, possibly a start-up software developer that has created something seemingly cool but not available for another few months. I might also bank on introductions of new technologies i.e. 3D imaging. We can also assume there will be an emphasis on "green" technologies.
