In the last few weeks, there has been talk of Apple filing a lawsuit against Motorola for having misrepresented its ability to produce microprocessors for Apple on a timely basis. This is essentially a repeat of the G4 fiasco that occurred in 1999, differing only in that Apple had not opened its mouth to the public too quickly. Steve Jobs was forced at the last minute before Macworld to change his product announcement, as the G4 lineup was supposed to have been 733 Mhz, 867Mhz, and dual 800Mhz and 1Ghz to ship in late august." </strong><hr></blockquote>
I read that as well - but a while back. This was in reference to an older pre-production revision of the G5 (0.5?) which did have a cache problem that caused many to think that yields would not be as high as initially expected (expectations were for it to start around 1.4GHZ). The problem was not with cache once placed into a Mac, as was suggested earlier in this thread, but rather a fault of the chip itself. The problem did slow down development, but was solved in a later revision (0.6?) that allowed the chip to soar past the GHz barrier. The G5 has not reached initial expectations, but it should in the next revision - for now expect the first models to top out around 1.4, but you shouldn't see anything under 1.0 GHz. FYI, these chips are being produced - it's just a matter of when we'll see them in an Apple machine.
It's also worth stating that Apple can't just start pushing machines out as soon as MOT is mass-producing a processor. I personally have no guess about whether we will see a G5 in Jan. or not - it's possible, but it would be tight. Bottom line: if Steve demo's a G5, I wouldn't expect one to ship for a month or so. If we get a speedy G4 revision, I'd expect them to be available "immediately" (2 weeks).
