Highly doubtful. Speed bumps will definitely be announced for the PowerMacs, however not up to 3 GHz quite yet. Jobs initially mentioned we would see 3 GHz machines later next year (to paraphrase) so I'd be looking for them more likely in the summer timeframe, shipping in the fall, or announced early fall and shipping immediately. 3 GHz iss too much of a speed bump from the current 1.6, 1.8, 2.0 lineup. I agree with the other posters and other rumors that 2.2, 2.4 and 2.6 would be more likey, and perhaps a 2.6 won't even be released, as the low end PM will become a single 2.0.
As for G5 iMacs, Apple will not release a G5 iMac:
a) so soon (relatively) after the brand new G5 chip has been released (only 6 months ago) - how long did it take before the iMac received a G4 after the G4 introduction in the PM?
b) before a G5 xServe comes out, and G5 PowerBooks are close to being completed. A consumer-level model will not receive a brand new chip before pro machines like xServe and PBs.
c) in general before other things are updated, i.e. the aforementioned PM speed boosts, G5 xServes, and also LCDs, plus new iApps.
Just how many major announcements do you think Jobs will make at MWSF? 😉
