BAD HARDWARE WEEK

Lets wait for June 6th.
By the way, Intel's 134 Core 2 bugs didn't make any launch delay last year. And strike on confidence of Intel's server manufacturers. By the way, that is Intel's only own original tribute to X86-64 architecture. :)
Personally, I think Barcelona benchmarks will be launched on June 6th, though processor delivery will begin later in Jule/August.
