I haven't heard anything about the analysis of the paper. Perhaps it is just as significant what they are not talking about as what they are talking about.

They should be able to trace the paper. Probably to a batch of 500,000,000 sheets produced for Wal-Mart, Staples, Office Max, Office Depot, and others. Of course, being A4, this would limit things a bit. (A4 is used in the US too, nice aspect ratio for use in copying.)
