Quote from Tomshardware: (same link as above)
Hes not 100% sure... so I think its just him reporting rumors from sites like Fud, so it doesnt read like hes in the know and knows something is off. He also saying its silly not to wait until the 6970 is out to see how that performs against a 580, before buying a 580.
Of course, I could just be wrong here, and AMD is simply doing a good job of maintaining a low profile to avoid cannibalizing sales of its fastest Radeon HD 5000-series cards. Sometimes, silence speaks volumes, though.
I’m normally fairly decisive, but this is one of those occasions where AMD and Nvidia are launching in such close proximity that it'd almost be silly not to see what happens with Cayman.
