I talked to an AKC rep a couple of shows ago. The change probably won't happen for quite a long while, but the plan is to split the sporting group into a retriever group and other sporting group. The working will be split into a "northern" group (huskys, malamutes, etc) and other working breeds group. Also, some of the non-sporting dogs will be moved into a "companion" group. As I said, don't expect this change before next year's Westminster.
I heard them talking about it but I'm not too sure about the details. It seems like so much more work than necessary, but it would probably be more interesting to split things up... that way you'd have more winners!
