FUD Zilla heard from its anonymous sources that AMD's Radeon HD 6900 (Cayman) series may not make the scheduled November 22nd launch date. The site claims at least some of the major players currently have no cards, no final BIOS and no drivers.
Just to assure you that this is not Nvidia talking, these guys are all unhappy as they were supposed to get some good sales numbers over the holiday season, as quite a few of people are excited about Cayman.
As of today, November 5th, at least some of the mayor players have no cards, no final bios and no drivers. They are saying the way things worked in the past they would have a small miracle to have full availability at launch. Of course, it's possible that the launch will proceed as expected, but availability is the key issue at this point.
