Why no Class D integrated love? (from manufacturers)

Unless I'm mistaken, it seems that Class D integrateds are not receiving the same attention from manufacturers as a whole. Sure there are the Peachtrees and NAD's of the world but by and large it seems the better class D tech is going into separates right now and that's somewhat disappointing to me. It's easy to find affordable separates based on the latest Icepower and Hypex modules but almost impossible to find integrateds based on anything but the lower end modules, for example the Nord integrateds.  Perhaps I am missing something? It just seems like this is an area that is ripe for some innovation. Anyone making "affordable" integrateds based on Hypex NC500 or IcePower AS1200 for example?
