In this article on the very exciting new Schneider lenses for m43, is this passage:
"The lens fits all Panasonic and Olympus m43 cameras. It also fits some Leica models when using an adapter provided by the manufacturer. Contrary to some reports in international forums and on photo websites, an adaptation to Sony’s E-Mount is not planned."
quote from NikonRumors
What Leica models would that be? No Leica camera that I'm aware of could mount m43 lenses.
