What Panasonic could teach us; Panasonic Full Frame

The Panasonic S1 & S1R full frame cameras are literally like a dream come true. I said "like", because it's almost a dream. There are at least a couple of aspects about the cameras that I think are missing, such as BSI sensors and small size. Their large (over 1 kilogram) weight should really help when handholding with a large lens. Their maximum of about 6 stops of image stabilization is really great, even though it doesn't quite match the image stabilization of the Olympus OMD-EM1X. However, being about $500 less than the Olympus and still having a sensor that's 4, yes that's FOUR times larger than that of the Olympus, these Panasonics could very likely succeed. There is one feature which I suppose could be considered missing, and that's Live ND such as in the EM1X. Their native ISO range starts at ISO 100, which can be a good thing and a bad thing, depending on the exact situation; For example, a lower ISO value can achieve better results, in particular dynamic range, in bright light; at the same time, however, a higher minimum base ISO might look cleaner in regards to noise. As for astrophotography, one of my passions, the Panasonic is what I think would be better of the two Panasonics, and on a scale of 1-10, my rating would probably be somewhere from 6 to 9, although at the time of writing this, the ISO results in low light haven't been tested yet, something that I'm very interesting. Honestly, however, what excites me perhaps even more is their alliance with Leica and Sigma, the latter which has been known to produce a variety of relatively affordable, yet high-sharpness, lenses. What other wonders will we witness from the advancements of photography cameras? In my opinion, the price of about $2,500 is still quite steep for the camera, especially considering the fact that the minimum price of a lens could be approximately $1,000.
