James,
I've owned Olympus and I love their glass. The problem with their DSLRs is a lack of technological sophistication compared with Canon and Nikon.

Now you have Panasonic and Leica adopting the format. Panasonic can certainly help in the technology area with better sensors and processors and Leica also has great glass.

But for me, the format is simply not practical. I'm looking for larger sensors, lower noise and the ability to use wide-angle lenses that actually cover wide angles. Looks like there's a 5D in my future .

Kinda makes you wonder what Olympus/Panasonic/Leica could accomplish if they applied their talents to full-frame DSLRs instead of investing all that time, technology and money trying to establish a market for yet another format.
