genetical (and other) research in dogs is still done and never stopped, though I don´t know when the last statistics of this disease has been done I doubt very much that they are 20 years old. Even if you take in count the different tastes of human beings it is very clear that there are breeding lines and breeding dogs that have an highly increased amount in cryptorchids in their offspring. As you wrote before: it doesn´t really matter if it is the pelvic-construction - what I don´t think is very likely- or hormonal problems (that are thought to be the main reason at the moment). As long as we don´t know enough about the genes themselve we have to go for statistics and most statistics on genetic diseases in dogs are done on a quite big population. In Germany German Shepherds, Poodles and Boxers have a very big population, most of their puppies don´t stay with breeders but with normal families, that didn´t buy the dog because it is from a special breeder or out of a special breeding line but it is from the next breeder around or the only puppy available at the moment. It is not very likely that especially this cryptorchid-lines have been selected or influenced by a special enviourment differently to all the others.
If you look at the breeds they have very different pelvics (dog pelvics aren´t that different anyway) but are all out of breeds that are in the unlucky situation to have breeders that go for special looks and therefore didn´t select very thoroughly for health, most of those breeds have over-avarage health problems of very different kinds. German Shepherds for example don´t only have orthopedic problems but almost every other disposition you can think of. Boxers didn´t only use sires with cryptorchid problems but also with heart problems, just because they were thought to be beautiful. The offspring of this sires caused problems till today.
Interesting new points of thinking and looking at problems are always worth a discussion and research, but shouldn´t change breeding policy to a weaker selection before they are proofed to be right. We had a lot of intersting new theories in veterinary medicine the last years, most of them turned out to be totally wrong a few years later, very few of them have been right.

P.S. Sorry for the sorry, in some ways it is very difficult for me to write in English and some translations are wrong or may be unpolite.
