It seems there is a small possibility that the next Four Thirds camera will be named under new E-system naming conventions.
Something Canon did with it’s 1000D and Nikon with it’s new D5000.
Please remember that we are a rumor site. We are not affiliated to Olympus or Panasonic. We get a lot of rumors which are sometimes contradictory. And we have learned in the past years that the big companies usually make last minute changes. That’s why we’re waiting before publishing rumors we have  so as not to confuse you!
UPDATE: A source claimed to know that the next classic four thirds camera will have an “OM” instead of a “E” signature.
