If you like the square format of your Hassy, then the Rollei AF 6x6 camera may be of interest. I have heard good things about it, especially the lenses. I am sure that it doesn't focus with the speed of a Canon or Nikon but I believe that it is the only AF 6x6 camera out there.

I found one on ebay with a picture
