Look how Olympus is going to tease us! What you see on top is the E-P3 successor and Olympus will not show it to us for now 🙁
UPDATE: There is absolutely no official detail yet about possible specs. They only say that they will release that new E-P3 within 2013. And the graph below states that Olympus will release the new PEN, a new OMD, a new E and a new high end compact camera by end 2013.
