AMD Cayman info (or rumor)

[xdan]

My opinion is that AMD is acting like a coward chicken...
I understand 2-3 weeks befoure launch, NDA to be respected, but 3-4 days befour launch is pointless. I mean what market advantage Nvidia should have if we know the true specification about the cards now.
1 week befoure launch we should know(this was the case of GTX 580,GTX 570) the true specification(core speed/sp/mem speed) and the official price.
I'm not talking about performance, just to know the specification .
Acting like that nobody would rush to buy 6950/6970 from the first day because nobody knows what the hack is with these cards.
If they are a true adversar and the have the right card in hand, Amd should have leaked more information about 6950 and 6970 and kill the GTX 580 and GTX 570 sells.
