I take it that you mean a true rangefinder, with split image focusing, plus Contax style AF and limited to the narrow focal length range of true rangefinder system?
If so, I doubt you will get much more than the Leica M9, and maybe another boutique M-mount digital rangefinder body from Epson, because rangefinders are now a tiny and shrinking niche in digital photography, with little hope of justifying the expense of developing the array of new AF lenses that you propose.
Let us balance our dreams against the evidence: RF's were already reduced to a small niche and abandoned by most makers by the rise AF film SLR's, with only the Leica M system surviving, and its survival probably dependent on "subsidies" in the form of purchases by collectors who never actually use their shrink-wrapped trophies. And now RF's are being made even more marginal by the new wave of mirrorless interchangeable lens digital camera systems (MILC) that use live view rather than an optical rangefinder for composition, and so offer a wide array of modern conveniences like: better AF; a WYSIWYG VF image that allows the user to see and check focus at off-center points, to preview DOF, and to zoom to check details far more accurately than any OVF; accurate parallax-free framing; a far wider range of focal lengths than any RF has ever offered; and the ability to use zoom lenses over that wide range of focal lengths. Digital rangefinders instead exist mainly to offer backward compatibility with existing RF lens collections.
Compared to DSLR's with continuing enhancement of their Live View options, which could in the future include adding options like an electronic shutter and an accessory EVF, other digital camera alternatives will rely heavily on a size and weight advantage, and that is squandered by moving to an unusually large sensor format like 36x24mm, which I will remind people again requires longer, wider, larger, heavier lenses to get almost any advantage over a smaller, more mainstream format.
I must admit that my "mirrorless camera system" format size hopes are in the opposite direction: that Nikon delivers what a bunch of 2009 lens patents suggest with a compact MILC system in roughly 17mm diagonal (1") format.
