Yes, Intel has provided seed units to system integrators and software developers so they can start system and code testing. However, those samples are covered by NDA that does not allow performance measurements to be published, including comparisons with competing products. Only Intel can

I feel it's a double edged sword. Usually when intel ships a great new part, all the sites are discussing it and 1 or 2 vague tests show up. AMD seems to use the path you describe below. Suddenly K7-MP 1.2ghz was there crushing P4 Xeon 1.7Ghz at the time. Suddenly opteron was there at 2.2Ghz
