No way!!! And I was sure Bill Gates would be doing it.
Predictions:
New Mac Pro. Except for the 8 core update, it's ancient (Aug '06) and *desperately* in need of an update... if they don't at least update that then they might as well just disband the computer division and concentrate on iPods.
Small Macbook Pro. It's certainly been rumored enough. Possibly flash based (cue whining that people can't store their full pr0n collection on it and they expected at least 500GB, and that it doesn't have a $500 graphics card in it)
Goodbye Mac Mini, hello xMac complete with the half decent (though not brilliant) graphics card people have been asking for, and a bundled EA game. IFFFF they can find a slot for it in their very carefully priced and structured lineup, and do it in a way that doesn't make it too much of an "Apple PC". Something like the Cube would work well.
To make up for the loss of the Mac Mini, the TV thing gets more flexibility - run apps, browse the web etc. Won't be as powerful and people will complain, Mac Mini will become a cult icon etc etc. Most of its market would be happy with the xMac, at the same price.
iMac untouched. The previous releases are only just becoming stable after all the freezing and graphical problems etc, it's not the time to go breaking them again.
Maybe a Macbook Pro redesign, if they want to update lots of things in one go and give themselves nothing to do for a year.
No new iPhone yet, and besides it's a MACworld event not an iWorld event. However I'd expect a 16GB iPhone (no other changes) shortly afterwards. Many of us with 16GB iPod Touches are waiting to upgrade to one.
Not sure about cinema displays. Personally I'd hope they keep them as they are rather than ruin them... Apple aren't very good at displays right now (negative blacks, gradient problems yada yada)
lol xserve (you can tell I'm sneaking a peek at the buyers guide here). Who the hell uses a Mac as a server. I guess they might refresh it

But really... do you need such a pretty server? Get a Linux box.
No iPods. They've just been done.
Maybe aluminium mice
Certainly not all of those or even a large chunk of them in one go, or else what have they got left to announce for the rest of the year? My suggested priorities would be the Mac Pro and this "xMac" that everyone wants. But then I don't run Apple.
