This is the one that really rang my chimes because it matches my tu-tu............
The GX100 looks promising but with a 10 MP, 1/1.75 sized sensor, it also has to have a lot of noise at anything above ISO200, approx. the same sized sensor as the LX2 Panny.
I liked the idea with the Sony R1 of a 10 MP APS-C "CMOS" sensor, only CMOS in a prosumer camera to date. Purportedly the same sensor that's in the Nikon D2X.
