UPC, Re: That's not the only piece of misinformation lately. There was the small matter of the suggestion that anyone buying a 32-bit Prescott now would have it magically "enabled" into 64-bit mode at some future date.
I didn't say that. I said that Intel already has 64-bit working in the current stepping of their chips, and they can enable it any time they want by fusing it on. In case you don't realize how fusing works, it is a one-time configuration of the processor just before it ships. No chips that have already been programmed (those that are on store shelves or in end user's computers) can be refused, only new chips. Intel will enable this feature whenever it suits them. We already know that Nocona is shipping and that Nocona has EM64T; furthermore, we know that Nocona and Prescott are the same silicon with different fuses enabled. You are trying to confuse the issue by arguing against enabling 64-bits in currently shipping processors, but as I said, that's not how fusing works.
Re: Read more carefully. They are also preparing to launch 130nm Northwoods (not EEs) on LGA-775, presumably due to the disaster that is 90nm Prescott.
The S775 chip mentioned here for Q4 launch will be Prescott based and have a model number of 720J. It will have both XD and probably EM64T.
My opinion is that Intel is waiting for the Extreme Edition / 700 series to have EM64T before they enable it so that from a product positioning standpoint, their mainstream won't have a feature that their high end is lacking.
