*confirmed* by AMD to ABT and also here:
Here is the email that i got from AMD
Demand for the ATI Radeon HD 5800 series continues to be very strong, the ATI Radeon HD 5970 remains the fastest graphics card in the world and the newest members of the AMD graphics family, the AMD Radeon HD 6850 and HD 6870, have set new standards for performance at their respective price points, and are available in volume. With that in mind, we are going to take a bit more time before shipping the AMD Radeon HD 6900 series. As of today, the NDA lift for information relating to the AMD Radeon HD 6950 and HD 6970 will be the week of December 13th. We will be providing additional information on these products, including the exact date and time of the NDA lift, in the weeks prior to launch.
Thanks for your continued interest and help in letting gaming enthusiasts know about these products. We appreciate your understanding and patience.
We are definitely going to have to wait longer for Cayman
