Regardless of performance, 3K for 20 MP in todays environment is a tough pill to swallow. Years ago, a lot of the pundits said 18 -24 MP would be the max amount needed. But by today's standards, thats like an old camera. Bigger size, more money, not sure how the noise/sensor issue will shake out, but it seems like there is a lot of Oly hype going on in the background with this one and not sure if it's going in the right direction for me.
For ME personally, $3K for 20MP camera is not tough to swallow at all, but 3K for a MFT definitely is. I have been and will continue to spend that kind of money on a camera body, my first FF only has 16MP but it was $8K, the Canon 1Ds II, just an example, and the replacement 1Ds III was about the same price, and fast forward to today, if Nikon drop their price on the D5 from 6K to $3K, I will order one right now, same for the 1Dx II, but I do have some hard time to spend that kind of money on a MFT.
With that being said, I am willing to spend that kind of money on a Canon , NIkon or Sony not MFT just because I am mainly a FF user, I am sure there is plenty of MFT fans here totally comfortable to spend that kind of money on a pro MFT because that's their system of choice.
