After a few recent announcements, Olympus just disclosed its roadmap of the micro 4/3 format.
It becomes quite clear that Olympus is concentrating a lot of efforts on this format, and that the perspective becomes more readable.
Nota bene: At the same time, Olympus UK reduces the price of an E-PL1 kit with the M.Zuiko Digital ED 14-42mm f/3.5-5.6 zoom lens, now at 750€ or £449.99.
