Hi Pavel. Maybe you should quit your job and devote all your time to this site! Ha Ha.
Yes, I also wondered if Panasonic or Olympus would launch a competing 4/3 sensor compact.
Recently though, Panasonic hasn't marketed so many "niche" cameras.
Other than the L1, cameras have been more mainstream.
I think a large sensor compact will inevitably have to be a niche camera; the large sensor will require sacrifices in zoom range that the average consumer won't be willing to make.
But who knows, maybe there will be some surprises...
As to the DP1, a comparison with the GRDII certainly would be interesting.
I imagine that either camera will have its strengths.
Perhaps, if I get a DP1, we could meet up for a day of shooting test photos?
