I know about Contax, I've even tested it years ago. AX autofocus wasn't
simply slow, it was a disaster. Still it doesn't mean that in-body AF
couldn't be done better - especially if we consider that instead of film
mechanism there's only a sensor to move. After all, weight comparison
between lens (group) and sensor chip is the cornerstone of in-body SR.
How many people said "it can not be done" before Pentax engineers just
came and did it?

Want some crazy suggestion? ;)
Future Pentax bodies will have in-body autofocus. It's much faster to move a
light sensor than tons of glass. And you'll have AF with any K-mount lens
(and others that you can mount via adapters) ever produced. Great, isn't it?
Why it still has a focus-ring... hmm, well, it's for a backward
compatibility and manual focus, of course.

In body AF has been done (Contax AX), it's MUCH faster to move the
glass and far less trouble to keep aligned.
