We tend to check the market a day or two after any product launch and we can tell you that Radeon HD 6970 and HD 6950 cards are still widely available. We don't like paper launches and this certainly was not one of them. 

Its been some 30 hours since AMD officialy let people post their reviews and start selling Cayman cards. So far it looks that the cards are selling well and that AMD has enough of them.

The EU market has enough cards and you can find many of them listed and available here.

Newegg in the US still has them and the prices we mentioned yesterday havent really changed. You can check them here.

In the UK we checked again and you can see that some cards sold at eBuyer but they are still available. You have all the necessary links here.
