I guess my point is at this point, had I not bought the camera I did, I wouldn't buy anything else and stick with my 7D for the time being.  Why by something that you know (granted everything will phase out eventually) is going to have a shorter shelf life because you can see what is coming already?
Youtube already has enabled 4K, and Vimeo is working on it.  Sure not everyone has the equipment for it yet, but it's trending that way.  Sure web delivery is smaller but thats not the point I'm making so much.  I should've stated it better.  I wouldn't buy any HD camera right now, I also wouldn't buy the JVC, but it's a good showing that the future is coming, and coming soon.
I'd wait for Sony or Panasonic to respond, heck even Canon even though they already fucked themselves with the C300.
