But days away from MacWorld Expo... here is a summary of rumors/news over the past few months related to Apple and MacWorld Expo New York 2002. You can watch the keynote yourself, and follow the action in the MacRumors IRC Channel.
PowerMacs
Last release: Jan 28, 2002
As always, predictions about new PowerMacs span the entire range. Early and subsequent rumors hinted at dual 1.4 GHz G4s toping out the PowerMac line... and even the occasional 1.5 GHz rumors... but with clear hints (one, two) that the G5 will not be coming this soon.
More recent rumors, however suggest that there will be no new PowerMacs until August and with speeds "in excess" of 1.2 GHz. This latter rumor coming from CNet, which tends to be have more reliable rumors than the standard rumor fare.
What information that did leak out, however, was the Prototype Motherboard that was somehow leaked and attempted to be sold on eBay. That particular auction was quickly brought to a halt, and photos hosted on this site were targets of Apple Legal Cease and Desist letters.
This prototype model featured DDR memory and Firewire 2 which suggests bringing those technologies to the upcoming PowerMacs, while other prototype enclosures suggest other minor changes coming to the PowerMac line...
iMac
Last release: Jan 7, 2002
LCD iMacs were released at MacWorld SanFrancisco 2002. While an early revision seems unlikely, CNet hints at 17" iMacs upcoming at this MacWorld.
iBooks
Last release: May 20, 2002
With a relatively recent update, as well as hints from Apple that the iBook would not head into G4 territory just yet, special edition G4 iBook rumors still surfaced.
TiBook
Last release: April 29, 2002
No serious rumors about TiBook updates are currently available... but 1GHz models are reportedly floating around... but not for this Expo.
iPod
Last release: March 20, 2002
With a 10gig upgrade only four months ago, ThinkSecret feels that a 20GB iPod will surface at MacWorld Expo 2002. Previous PC iPod rumors continue, but recent hints against such a release at this time.
