I am thinking of moving from the large (and old) Sony F828 .. it was a very early 8MP camera with full size zeiss lens and DSLR style body, but permanent lens. It takes fantastic pics but I'm tiring of the great honking size of it. I wanted a true DSLR at the time, but the least expensive model was almost $2000, so at $900 the Sony fit a combination of wallet and desire.
I was thinking of moving to the 4/3rds design, myself. I'm still researching
