I sold my GH2 and bought a GH3, sold the GH3 and bought a GH4 and have now bought a GH2 again just cos i still prefer Moon T7 on the GH2 to the GH4! I never think of the GH3. If you've got the 4 you've kind of got the 3 plus, what do you want from the 3 you haven't got in the 4 that would make it worth keeping, GH2 out on it's own.
