It's possible that the 5870 doesn't match 4890CF because they spent some of the extra power on IQ improvements like angle independent AF and more AA modes. Or the drivers aren't mature at this point. We will know after a few more driver versions.

Fermi will probably be competing with 5x90 and that could be just a higher binning or an actual refresh. To keep margins high with an expensive chip and expensive board they will want to have a significant performance lead. Otherwise this could be the generation that brings ATI and Nvidia market share into parity. I hope they can pull off 40% faster then 5870, but I'm keeping my expectations low.

Right. But it doesn't really matter because Fermi won't be fighting GTX285 SLI or 4890CF.
