I don't know - bringing out an M-lens compatible digital doesn't seem like a bad idea to me - a lot of "purists" may want (or think they need) digital, but have a lot invested in lenses, and this way Leica doesn't lose customers for those who go in that direction.

Mind you, with the crop factor of a smaller-than-full-frame sensor, it's not quite the same (and I think Leica did come out with M8-specific lenses as well).

However, I occasionally read some of the Leica/rangefinder forums eleswhere, and while many Leica fans seem to like it, a decent number complain about it regularly as well - in particular, apparently the M8 has issues with a magenta cast in pictures - "fixable", of course, digitally, but annoying to many who spent quite a bit for the camera.
