I ordered a G4 450MHz pretty much the day they were announced. After some back and forth with the dealer, I was sent two machines - one with 450MHz as originally announced, and one with the same specs, but only 400MHz as initially shipped. Somehow, my dealer was able to get a few of the initially very rare machines with the original specs, and I was lucky enough to get one. I don't really recall why I had been sent two machines, but I know that I was instructed that this would happen, and I had to look at the specs printed on the box and send back the slower one.
