There is almost no more doubt that Sony will announce the new NEX-3n next week. The NEX-7 successor will follow in late Spring-early Summer. But we just heard that also Panasonic may have an announcement very soon! Not sure yet if they will introduce the new GF or G or both at the same time. If you are waiting for some Olympus news than guys you may have to wait a lot! The E-P2 and the first f/2.8 constant zoom may come in June only.
Overall it looks like Sony, Panasonic, Fuji and Olympus will wait for the second half of the year to announce the more “heavy” stuff. SO let’s hope at leats that Samsung FF March release rumor wasn’t just a false hope!
