Who's to say indeed. The big boys, at least Nikon, eventually got to offering a cam without an AA filter and I am sure that it was because of Leica.
The BW thing might take a longer while simply because most think that they already have that option anyway in their cams.
I was converting color photographs yesterday to BW and I was thinking to myself how good can it still get with the Monochrom? I mean, the current state of BW is already fantastic. Leica lenses paired with a good sensor hitting the soft spot in that time of day will produce technically great images.
So I totally agree about PROs showing us the limits of this new sensor and also how far it is from what can be done today. i'm thinking it won't be that great great.
Btw, I was looking at that photograph that you developed of my daughter yesterday in light of this Monochrom thing. Totally different worlds. I was actually thinking yesterday, "I wish I had Jeff for a neighbor"
