Macworld Expo starts one week from today, so the anticipation & rumors have reached a fever pitch. Apple’s announcement of new Mac Pro & Xserve models today certainly means they have something much bigger to announce in the keynote.
I think it’s a pretty safe bet that Apple will introduce a subnotebook, possibly with a touchscreen.
I’m also pretty sure Apple will officially kill the hard drive based iPod. Flash memory is now available in 64G and larger sizes, so I wouldn’t be surprised to see an iPhone or iPod Touch with 32G or 64G of flash storage.
Other likely announcements: Blu-Ray drives in laptops, iMacs, and Mac Pros; a new much more capable Apple-TV, possibly with Blu-Ray, a web browser, and DVR capability; new displays with built-in iSight; and of course movie rentals in iTunes.
