You know that M.Zuiko 17mm F2.8 is already manufactured. This patent will relate to it. The other optical systems would be examined for the same period. However, they do not have a released sign.

However, Olympus releases only a body. I hope that Olympus releases a lot of lenses. However, Olympus seems to plan a new body. It resembles Panasonic G1/G2 and GH1.
