GK104, the 4 in the end has always been indicative of midrange/performance part. just like 6 is lower mainstream and 8 is low end. And the existence of GK100 and GK110 indicative of high-end is very well known, though nothing else is really known except that at some point they were/are in the making. @ Casecutter They didn't know exactly what AMD would bring, but they had an idea a long way back. Specs were known, there were some leaked figures, etc. So they already knew it would be close. They also had the previous generation to compare with where GF114 (midrange/performance) was faster than Cypress (high-end), even though it released later but it's what GF104 was suposed to be. So if Kepler is much better than Fermi it was relatively safe to assume they could do better this generation. But they didn't just stop making the high-end chip, who said that? They only scraped it (if they have canceled it at all) once it was known HD7970's performance. According to rumors, things were not going well with the chip, so instead of releasing another cut down chip like GTX480, they cancelled/post-poned it. And again IF they have done so at all, because no one really knows fuck about it. If GK104 couldn't compete with Tahiti, they would have forced another cut down card like GTX480.
