Let's see, D.--- Ricoh digital has no real customer support in the US. They use a lot of 3rd party parts, I question the integration in some of their products. They have had a checkered history as a marque, particularly in the US. No resale value stateside. They make a lot of bizarro niche stuff----it looks like their designers have fun (although the look is butt-ugly) but their manufacuring doesn't always seem up to the task and marketing doesn't seem to have a clue. In addition, Ricoh seems as caught up in the megapixel wars as anyone else, "big boys" included--- I doubt the integration of optics and a 10 megapixal sensor suffers any less then most attempts in the compact digital camera realm. In fact, Ricoh has a bit of a rep for high noise levels, even at lower ISO speeds. Something it shares with many Panasonic offerings (in fact I heard a rumor that Ricoh uses similar software for noise reduction).
Nitpicking this particular model, based on Ricoh's specs and press release--- it may not be supported by Adobe Camera Raw. Electronic viewfinder? Fine on a digital SLR but an optical finder would be better for the pursuits practiced by people in this forum---no drain on batteries. Since it seems to have a shoe on top, one could substitute an accessory optical finder (such as the superlative Leica finder), perhaps. If the Lens zoom range extended more into an optical moderate telephoto (say to 35mm equivalent 135mm and bugger the digital zoom) it would be less a specialty camera and more useful for most, and more particularly, me. As it stands, if I owned a GX 100, I would feel compelled to carry a 2nd camera as well, and if I did that, why not just use a Digital Rebel and a couple of lenses instead?
But, by all means, someone please get one and report, after the camera is finally released.
