Looks like you didn't finish your thought?
I like some of dpreview's reviews. I like the existence of their studio shots but don't think they always carry out those tests well.
For sensor performance I really prefer to use DxOMark. YMMV, of course... but DxO shows the advantage between the D600 and the K-5 at equivalent resolution is about 2-3x the advantage between the K-5 and the K-x.
It looks like DxO hasn't tested the D7100 yet.
