Sorry if this is a repeat but there have been alot of emails
and I haven't combed all of them.

It isn't that the number for BlueGene was leaked more than
that all numbers have been always available before the list
is published bi-annually.

See http://www.netlib.org/benchmark/performance.ps

This file has always been updated as the numbers become
available.  Sometimes there are duplicates depending on
the configuration of the systems, but the numbers are there.
I check the list before SC2002 for an entry I submitted for
a large Xeon cluster. I saw the BlueGene number there before 
SC2004.  It was pulled about a week before-hand.  This chart
also had the 51.7 Tflops number for Columbia even though the
announced number was still 40+ Tflops.
