Ok i know a jump of 1 Ghz in one revision is unheard of, but before you flame me hear out my logic. We all know that Mr. Jobs stated that PM would reach 3 Ghz "by this time next year." This would place an annoucement of 3 ghz PM at the latest by the end of this June. That gives us about 4 months untill then. Now even if apple announced a PM at around 2.5 Ghz next week(which probably wont ship untill next month, using info from xserve ship dates), it would not make sense for them to then announce a speedbumped version of 3 ghz just 3 months after the 2.5ghz systems ship.
So im guessing that the next update to the PM has to be a 3ghz updates, now when this will happen is another question. We now know that IBM is ramping up production of 2.5ghz G5's, but that dosent necassarly mean that that is the highest clocked g5's they are producing. I wouldnt be suprised if they are producing 3ghz chips as we speak but in lower yeilds. So apple will either announced updates PM's next week at 3ghz...with the 2 lower modles shipping in a month and the 3ghz system shipping some time after that, or they will wait untill IBM has enough 3ghz chips to make that annoucment, which would peg that at around the time xserve's ships next month, so 2 lower modles avaliable immediatly and 3ghz shipping in a few weeks.
Hence fulfilling Mr. Job's prophecy
