The hd 6970 must significantly beat the gtx 480, otherwise it will quickly become irrelevant. It is within the realm of possibility that nVidia will release a new card (probably not a new generation but still using a naming scheme deceptively making it seem as one). I dont approve of nvidia's PR tactics, but a fully unlocked gtx 480 with a higher clock speed that could beat the HD 6970 (if it is only slightly faster than a GTX 480), and a fully unlocked gtx 460 with a higher clock speed that could beat the HD 6870 or HD 6950 are all within the realm of possibility. AMD probably knows this and must release the hd 6970 with enough power to beat any nvidia response until it is time for the hd 7000 series.
