My plan here is to create some random waffle that may or will not be true in a couple of months, so that everyone can have a jolly good tin barf when I'm wrong. At my expense.
OK, it's check date now, and I reckon that this time next month the high-end Apples will be running with PPC 970 processors supplied by Big Blue themselves. I expect these systems will be XServes, and a couple of the high-end PMacs.
Within three months, another % or so will have been shaved off all the existing G3/G4 stock, and some 970-based systems will be on the market.
Watch as I dig my time capsule into the mud, so we can all see how silly I look in years to come...
