Or.. Caveman is 100% right, which wouldn't surprise me, and google in fact is rolling out a new algo, running on 64 bit machines, with a 40 bit index. Given what I've read about how Google does their hardware upgrades, this would make total sense. The new algo running on the new machines could easily include the above components, while the old one just putts along until they replace those machines over time. And all sites launched since march 04 are being run on that new algo, exactly as caveman suggests.
