First Question was about the loss of the MAS.
Panasonic answer below

Panasonic: Our main priority was image quality, both for stills and movies. For our former models, the GH1 and GH2, we developed a special sensor that was a little bigger than Four Thirds. However, because we wanted to make so many improvements with the GH3, we didn't have a larger sensor available. The Four Thirds-size sensor was what was available from our sensor group .
