Hello David,
I don't think getting a comparatively noise free live view is as  
simple as a firm ware upgrade. According to my source (an engineer at  
Sony) the reason that Live View is only recently showing up in APS  
(and larger) CCDs (as opposed to point and shoot CCDs) is that the  
larger CCD's need top be redesigned to run "cool" . The problem is  
that larger CCDs (or CMOSs) if left on continuously tend to warm up  
and as they get hotter they start to generate more noise resulting in  
a lower quality picture from Live View. Sony had to redesign their  
chip for use in the R1, which was the first larger CCD live view  
camera, to be a cooler and thus lower noise chip. If what I have been  
told is true and should Leica decide that they want to incorporate  
Live View in the R10 they need to choose a chip which will run cool  
when continuously on or at least produce a low(er) noise image when  
warmed up. Hopefully this will have been taken into consideration in  
the design but after the M8 magenta issue I am not too sure! ;-(
Cheers
Howard
