I've been shooting with the PMW-200 for a few weeks now and I love it. The 50Mbps HD422 codec and 4 channels of audio fits the workflow better with my F800. And I find the camera much easier to hand-hold and shoot run and gun than my EX1. There are many things to like, and only a couple of complaints, such as no S&Q button. My EX1 is now for sale if any is interested.
Here's some surfing stuff I shot a couple of weeks ago when I was testing out some settings. http://vimeo.com/49126061
Had a hands on myself last week and generally loved the camera, the only change I didn't like was the fixed handle. I almost always have my EX1's handle at different angles to fit the style of shot I want and going back to a fixed position was a serious and difficult adjustment. Working fast at mid height on sticks cataloging race horses and having to make fast focal length changes was just plain painful, but other than that I found the camera superb.
