Apparently Intel doesn't want you to have those nice shiny new Northwood P4's for your older 423 pin motherboads to upgrade with according to reports over at The Inquirer. Apparently they aren't for the end user, just the boys in the suits that want to sell you that bright and shiny new system. Almost smacks of the Rambus fiasco when they wanted to force you to use that memory if you wanted an Intel based system.
