Wal-Mart already sending Black Friday price-list cease-and-desists

Wendy sez, "If it's fall, these must be cease-and-desists for Black Friday ads. This year, they seem to be coming earlier than ever, as Wal-Mart sends pre-notifications against future posting. Chilling Effects has the story:"
Instead of waiting until Black Friday price advertisements leak and firing off DMCA notices, Wal-Mart seems to be opting for a trade secret route this year, sending pre-notifications to consumer sites such as bfads.net warning that any early release will be unauthorized. The warning won't be effective unless Wal-Mart can demonstrate the listings are in fact trade secrets.
