We'll have to wait and see. It would be disappointing for AMD to have a 6870 which is slower than the 5870, but even that is nothing more than a rumour (on both the renaming and the speed).
As for Fermi being only slightly better than AMD's tech, I guess you could argue that being the first gen, there's plenty of development to go, while AMD's current architecture is longer in the tooth. Having said that, the next AMD release (after 6xxx) is meant to be new architecture anyway isn't it? If so, we may just see AMD playing catch up to Nvidia again.
What I don't understand is how AMD can do no wrong in some people's eyes. "It's better than Nvidia's renaming" - aside from Nvidia shrunk the die from 65nm to 55nm? Can't see AMD doing that...
At the end of the day, they're both companies, they both have marketing divisions, whose job is to basically mislead people into buying products. One is no better than the other, and the product that suits you best is the one you should buy.
