RichRMA: Looking at the high ISO samples and test images, it's clear that 24MP is pretty much the limit for an APS sensor. They should probably stop at this point and wait for the technology to catch up a bit.
@iudex you are totally right : d7100 is probably the best actually ... but not alone! togheter with the k5IIs!! ;)
pretty easy in this way!you are comparing high iso from an old camera (canon 7d is from 2009) with this newer nikon!there 's a 4 years distance between those two models which in hi-tech evolution it's a lot!
George Veltchev: The name K-5 II sounds suspiciously close to 5D MarkII at least ...and why not, this can be a good starting point for the new camera ;)
or like pentax 67 II which is a little better, for what I can remember ;)
