MacRumors is reporting that the organizers of the MacWorld San Fransisco 2009 have extended early registration until December 8th.
If the rumors are correct, this year promises to be exciting due to the hoped for updates to the iMac and Mac Mini, as well as the expected refresh of the remainder of the Cinema displays.
Also expected (however unconfirmed by Apple, of course) is the announcement of a 32GB iPhone. Previous versions of the iPhone have been limited in size due to the availability of larger, single memory chips. However in August, Toshiba announced that they would begin mass production of higher density 32GB chips in the 4th quarter of 2008. These chips could presumably be used in future iPhone and iPod touch models.
