Update: a reader sent me another picture of the Olympous E-7 Four Thirds camera:
Olympus did develop an E-7 DSLR based Four Thirds camera, but instead of releasing, they decided to merge the Micro Four Thirds and Four Thirds lines and concentrate only on MFT products in the future. A picture of the Olympus E-7 camera was shown during an official E-M1 presentation in Germany (image source: Pen-and-tell).
