The new Ricoh GR looks interesting:
Big sensor (full APS-C), very good 28mm f2.8 lens, intervalometer, 245g (8.64 oz) with battery and card.
The sensor is 8 times bigger than earlier Ricoh GRD models, but the camera is not much bigger or heavier.
The MY1-3 controls enable you switch immediately to your KAP settings.
The GR has the Pentax Time and Aperture priority mode (TAv) where you can set both shutter speed and aperture and the camera automatically adjust the ISO. This sounds like a useful KAP option.
At f2.8 the corner performance destroys the heavier Nikon Coolpix A (more expensive & no intervalometer):http://www.dpreview.com/previews/ricoh-gr/5

The only potential disadvantage I can see is the lack of anti-aliasing filter. Urban Kappers are going to have a problem with the moire fringing (roof tiles and bricks etc). It might be easy enough to remove in raw processing.
Note: Max shutter speed wide open is 1/2000, as you stop down it increases to 1/4000 at f5.6 and smaller apertures.
