Intel released the NDA from various web sites a week or two ago, and Intel
is now selling it in the US (I think today was in fact the official
launch), so I think benchmarks are safe - you can buy the dang things on
the street.

I don't know what availability is, of course. But I doubt that Intel would
mind Nehalem benchmarks even if it were a paper launch - at least from my
personal experience, I've not seen any bad behavior (and plenty of good).

Ahh, ok.
