I have a good news and a bad news. The good news is that we received new confirmations from other sources that the G3 is the next camera Panasonic will release. And the improvements the G3 will bring over the G2 will be major than the improvements the G2 has on the G1.
The bad news is a no-surprise. Although the Panasonic G3 could be announced soon (February-March?) we were told that the camera will be available in Stock only months later! Seeing that in US the GH2 is still continuously out of Stock this sounds again a little bit frustrating.
