This looks like a really exciting camera with some pretty impressive capabilities both on the video and still side. The V1 is really maturing into a serious camera I think.
Some standout details for me:
20 fps RAW continuous focus, 60 fps fixed focus
1200 fps low res video
Modular - strip it down to slip in the pocket, add grip, viewfinder etc as needed
Use it with all my Nikon lenses, not new I know, but a 20 fps action camera with my existing 70-200 sounds impressive
18 MP high ISO capability - be interesting to see how the dynamic range etc compare to the DSLR's
I think this could be a serious traveling underwater and wildlife camera particularly if Nikon get serious with some WA lenses; actually I see they make a 6.7-13. Hmmm getting better. Now what about housings Nauticam?
