Well, the biggest news is the speed-bump of the PowerMac G4. Overall, rumors regarding the G4 speed bumps were relatively accurate - and even exact specs posted 1-2 days ago on various message boards. Of course, it was impossible at that time to distiguish the real specs vs the fake ones. A consistent rumor though, was that 733mhz would become low end. This is pretty remarkable, as the 733mhz was introduced as the high end machine only in January.
As well, the new G4 Case was accurately depicted in the leaked photos from MacOSX.org -- despite claims by many that these were "obviously photoshop-ed images".
Finally, the ever-elusive LCD iMac and Apple Handheld... these rumors will most certainly make a comeback in MacWorlds to come.
