Leica M or Sony RX1?

As will go from my recent threads on this site I am in the process of replacing my Leica M9 by either the new Leica M or ...another camera!

I have Leica Summilux 35mm and 50mm and Elmarit 28mm and 90mm and I shoot landscape, architecture, interior and family.

I have studied the extensive information about available cameras thereby trying to get close to the my "ideal camera"

Some key elements in  my search were: portability, absolutely no large heavy Nikon/Canon/Sony - excellent IQ (FF), coming from Leica makes it difficult to live with lesser IQ - High quality fast lens - Anti Shake, to control my rather shaky hands - EVF/OVF - or minimum a top quality articulated/tilting LCD, but with preference for a VF - high ISO/noise performance also in low light. I dislike the need of carrying around separate lenses.

Options:

It is clear that the camera I am looking for does not exist and that one has to compromise!

So far I feel that buying the new Leica M is one of the better options, but the weight is somewhat worse and no AS.

Also the Sony RX1 intrigues me tremendously, but no AS and just the very good 35mm lens. No articulated LCD and a VF is separate.

Shake: As far as  "shake" is concerned I wonder, having in both cameras (RX1 and Leica M) a FF sensor and a very good ISO/noise performance, whether this will in fact limit my shake-problem because of the ability to shoot on average at much higher shutter speeds than is possible on my M9, also in low light.

Focus length: In case of the RX1 35mm is the limit. I noticed that 65% of my shots are in 35/50mm and 26% in 28mm ranges. I could crop quite a bit to get a 50mm and a tele-effect, but nothing can be done about the 28mm. On the other hand 35mm is kind of close to 28mm.

I do look forward to read your comments!

Thank you
