Well if it is not a big deal than there shouldn't be any reason for D700 users to be holding onto their old cameras so tightly.
Anyways, having a 15+ megapixel DX equivalent allows DX users to upgrade without switching all of their glass and still shoot higher-res than D700 users. And if the ISO performance is about the same... it's almost as if they have a D7000 built-in (maybe even better since the D7000 doesn't quite perform as well in low light as the D700).
From the examples ive seen the iso performance is NOT as good as a d700, it appears to be about one stop worse--similar to a d7000. I would imagine that the resolution might make up for the increased noise which would make the claim that it performs as well as the d700 not complete bunk. However this isn't a consideration when shooting dx.
