dslr HD video capture is nice..but its not a natural way to capture video the way you hold
an slr camera. Of course they have dslr rigs to make using the camera in video mode more natural..but its just more added gak not too mention it looks a bit cumbersome to get dialed in. You will get more capture options with a dedicated video camera than you will with a micro 4/3 cam. With a video camera it helps to have some heft makes for smoother video.
Course try pricing out a pro level dslr from Canon or Nikon.. ( a couple grand for body only) add the video holding rig(unless you plan to use a tripod for every shot), lens, external mic.. um your now over budget!
Good luck .. read the reviews see the sample clips.. find out what movies/commercial or other pro footage used what cameras.
imo- micro 4/3 = fad..kind of a gimmick..do you have to up size video captured with micro 4/3?? just a question Im not sure.

Look at the Pan/olymp MicroFourThirds offers.
Cheaper than canon and superior lenses for less bucks.
Lots of videos on youtube where the panasonic especially are close to equal to the 5D II.
In any case if you can wait till Photokina, do that.
Lot of companies are expected to bring out interesting products that will fit your use.
Whatever you do. Take a camera with you at all times.
