Unreasonable predictions
Obviously $4K for an iMac wouldn't fly, and Apple knows that. There won't be a $4K iMac. And with the economy the way it is, Apple isn't about to introduce something as pricey as a wireless screen. Yeah it would be cool, but nobody would buy it (at least not enough to justify).
My predictions (not based on any knowledge other than past Apple history):
-iMacs bumped up in speed. Middle model gains 17" monitor, low-end keeps 15", high-end keeps 17". I predict no 19" iMac for at least the next 12 months.
-PowerMacs might get a speed bump, but I'm leaning towards that being a March-or-so announcement. If there is a speed bump, nothing else will change (no USB2, no FW2, no Bluetooth). Those updates will come in Spring or Summer. I wish they were sooner, but I don't see it happening. Possibly now using the 4X DVD burner though, although I see that happening quietly without a major announcement.
-iBooks, eMacs get a speed bump, and nothing else.
-PowerBooks get nothing (previous announcement too recent).
-iTunes 4, and some iDVD update shipping. iPhoto 2 discussed or shown, not ready yet.
-FCP 4 shipping.
-Major iPod revision. 5GB gone, 10GB and 20GB drop in price. Ability to connect CF cards and preview photos on screen. Sync new iPod with iPhoto 2.
-XServe speed bumped, maybe getting FW2.
-Lots of Rendezvous demos, announcements of compatible third-party products. Other than hardware announcements this will be the focus of the keynote.
-Promise that "at least some" of Mac models for 2003 (full year) will still boot OS 9. In the long run this will mean the lowest-end model of each machine. First machines not bootable in 9 will be the revised XServe (are they bootable now?) and new G4's to be announced in March.
-Quark will demo Quark 6 for OS X, claim how much they love Macs, and will get boo'd. No delivery date promised. Intuit will demo QuickBooks for X, although it'll be a crappy upgrade other than being carbonized.
And my "going out on a limb" predictions (with no basis in fact):
-iSync (with related changes) will sync with Exchange Server (Mail, iCal, Address Book).
-AppleWorks 7 (or whatever next version is) will use Word/Excel file format as native format. Not shipping for a while, but announced.
Those last two will seriously pi$$ off Micro$oft, who will threaten to stop updating Office for Mac. (I see a serious Apple/MS rift approaching in 2003; just a gut feeling.)
Again, just random thoughts.
