Last week, AMD’s CEO Dirk Meyer mentioned in a conference call that they would be releasing new graphics cards this week. From Anandtech:

We’ll be introducing our second-generation of DX11 technology into the market with some launch activities actually next week. We’ll be shipping all the family members of that product line I’ll call it, by the end of this quarter, and total volume think in terms of several hundred thousand, or hundreds of thousands of units.

He did not give any further details, but now there are new leaks about these graphics cards that are to be released soon. From Guru3D

Every time, the same accident happens. Someone, somewhere, lists the cards before their official release debut. Hehe, well this time it’s a Dutch etailer called Informatique.nl that got listed Radeon HD 6850 and Radeon HD 6870 at 190€ and 255€ respectively.

The rumor is that these will come out on October 22.
