Really, the spanish DSLRmagazine is becoming one of my favorite websites. They know how to make interviews!
A lot of infos were given by Mr. Yoshiyuki Inoue and Mr. Shozo Katagiri form Panasonic. You can read the google english translation by clicking here.
And here the key points of the interview:
1) Panasonic doesn’t work on a “double-capture sensor” because of the complex patent system
2) No Global Shutter for now
3) The new cameras G2 and G10 not only incorporate general improvements to autofocus by contrast, it also will provide better results (especially autofocus speed) with the objectives Four Thirds, when used via adapter.
4) We are not ruling out the entry of new “players” inside the MicroFourThirds world
