According to Wikipedia, the G5 was introduced in 2003. And Wikipedia also states the G4 being introduced in August of 1999. I don't know when the G3 was introduced, but with a four year difference between the G4 and G5, perhaps 2007 is a possible time frame.
However, I agree with the assessment that the next major step for Apple will be the dual-core machines. Perhaps also quad-chip machines, as some PCs are now coming out with. I would think a next-generation chip would be 2007 at the earliest. Maybe late 2006. Perhaps IBM's recent Cell chip might be part of that?
