Much to the same that you and the collective rest of the blu camp continually ignore the basic query to provide proof that they are not.
It's not incumbant upon anyone to prove that something unproven and undemonstrated does *not* exist. A white paper is a list of agreed upon specs. It is not a product in production.
It's incumbant upon a group claiming that something *does* exist and is ready for replication to provide accountability that it is.
This is the manner in which products have always been verified. HD DVD and BD zealotry, on either side, don't change this paradigm.
See my example about the "readiness" of 100GB BD replication.
