This camera will be huge in certain markets. One in particular - Astro photography! Put this puppy on a 10" to 16" telescope lens ( longer than 1200mm, darker than F8) and you could get amazing galaxy photos, with short enough exposure to make up for atmospheric distortion.
Hey DPReview, when you get around to the full review, please answer this question: How does the remote live-view look through the ethernet port and/or wft-e6 transmitter?
I do a lot of remote shooting with my 5DmkII, but I'm always disappointed with the frame rate of the remote live-view over USB. I estimate the feed is no more than 10 fps, even in good lighting (probably a bandwidth issue). The HDMI port gives me a nice, crisp 30 fps, but I'd prefer to tether my camera with only one cable. Unfortunately this isn't one of the specs that Canon publishes, so I'm counting on your review!
