Looks like the speculative comparisons to amd cards got a bit out of hand indeed, I guess that's because there's just not much information about Kepler still.
I really have no idea what to expect (in contrast to GCN when AMD released the whitepaper and some educated guesses including unit count from july 2011 turned out to be quite accurate).
The family is built on tsmc 28nm, that's for sure. Everybody also expects GK100 to be a much larger, but also faster chip than Tahiti, and (in contrast to earlier families) launch somewhat later than GK104, which supposedly will launch around March/April.
Since there was no whitepaper for Kepler well in advance, I take that to mean the changes (at least as far as it would have implications for CUDA) will not be that extensive as they were for Kepler. Virtual memory was promised (so I guess similar to GCN in that area).
Since it seems there's still some debate over whether the chips will have hot clock, discussions about unit counts etc. should be taken with a grain of salt. It is also unclear if gk100 will be quite different internally to the rest of the family, as it was with gf100/gf110 and the rest (though rumors talking about gk104 being a "fermi/kepler hybrid" could indeed point to that, as would the later supposed release date).
So, any halfway trustworthy specifications I missed?
