Me, I don't care what they do, as long as:
- My lux 35 asph is a 35/1.4, not a 45/1.4, 50/1.4 or 55/1.4 (i.e. full frame)
- It's no bigger than an M7 and uses a compact battery model
- It has the MP viewfinder
- It's as quiet as the M7
- It can shoot 2 fps
- It produces raw files of high quality, 10MP or more, preferably 15-25MP
Apart from that, all other considerations are secondary IMO:
- Price (OK, under $6000 would be nice, but what I'd be willing to pay depends on image quality. $5000-$9000 seems reasonable for the professional market.)
- CF/SD, don't care what they use
- LCDs/buttons/menus/connectors/tethered operation/etc, can all be left out AFAIC; just an ISO setting and a card slot
- Manual or motorized shutter cycling, don't care
Between an M digital, R9+DMR, and whatever Canon DSLR is current I think I'll be quite happy. A good set of tools with different uses.
To me, a 1.5 or 1.6X rangefinder isn't particularly interesting. Interest would drop very quickly the further it deviates any at all from full frame. I don't think too many would want to buy 24 ASPHs to use as big, slow 35mm lenses. A 90% (1.1X) might be OK but at that point they might as well make it use the whole image circle since it's just a matter of cost, not physical limitations (like the DMR having to physically fit in the R9 film gate).
The R9 is a really quiet camera actually. It has that same nice muffled clunk sound as the M6/M7/MP. Not like the rattly Bessa L/T/R, or whirry Canons. (I haven't touched a Nikon in many years, but remember my FM2n sounding more like a Bessa.) So a cloth shutter isn't really needed to keep it quiet. Actually, I don't think the M6 and M7 sound terribly different at all.
