I have to say, the prominent disdain for both the S2 and M9 are puzzling to me. Healthy skepticism is understandable, but from where I'm standing these are (assuming the M9 exists, is FF, etc) attractive looking products. The S2 with normal lens isn't priced too much higher than the Hasselblad H3Dii-39 kit, and while it is shy a whopping 1.5 megapixels, you get an integrated system promising faster autofocus, faster write speeds/general performance, and vastly-improved handholdability. Those speed gains aren't exactly difficult targets to hit with an integrated, new-from-the-ground-up system, but I can understand a "we'll see" mentality. It is the attitude that the idea of the product (a small, handholdable, fast-performing medium format digital, essentially a bigger-sensored D700) is flawed that baffles me.
I suppose my point is that for years Leica's been mis-stepping left and right, out of the gate and obviously. These things certainly seem like good ideas that, if well-executed, are exactly the things Leica should be working on.
That said, any suggestion that the S2 is already selling well seems suspect.
