Dear Brian,
That is exactly what I thought, so with higher cost (new electronics, fees) Panasonic can also enable this on future generations. But it proofs for sure that they have technical potential to improve much more very soon (beyond Nikon/Canon).
In the past I looked into a iRiver gadget MP3/4 player on which you could load Flash applications (and write yourself), but firmware hacks are even more down into the electronics. Pretty interesting outsiders can "look" inside a camera that deep...
Wait, I remember reading stories on Canon. Let me google, look for example here:
CHDK Wiki
It is getting close to open source programming. Then Panasonic can sell it as a piece of hardware without software (so no video fees) and at home you install the software to support photo/video/MP4/Etc...
- Hmm, let us keep it this way
Best regards,
Joep
