"Our source claims that Zeiss is working on a digital rangefinder with a Sony sensor, he goes further saying that unlike all the current dRFs the Zeiss dRF will use a CMOS sensor". (source: ZR)
This is what Zeiss had to say on this topic few years ago (September, 2006):
Q: There are rumors that Zeiss will eventually have its own digital rangefinder camera body that will accept the M mount lenses. True or false? Will it be Cosina-made? Full 24 x 36mm sensor?

So, is now the right time? Right before Leica launches the full frame M9?
Zeiss currently does have a film rangefinder product - Zeiss Ikon (product page):
