When browsing appleinsider.com, I came over this in the rumors forum. The author is Dorsal M, and the posters over at appleinsider seems to give this guy a lot of credit. Could this be what we'll see in July? "The PowerMac G4 as we know it will be retired. Well the architecture will at least. We will see changes to the system bus, processor and general layout. Motorola has been hard at work with the 130nm G4. It will scale nicely (at least 1.5GHz by the summer) and have improved bus features. Memory access will be stellar. And you'll see why. not only will DDR SDRAM make a debut but it will not connect to the processor iin a conventional manner. More to come. Cache will also be increased on the processor level. Twice what is seen now. You will see a collaboration with another hardware company, but this will not surprise some of you in the know."
