GH3 has most likely Sony sensor

If it was a Panasonic sensor, this simple question would have a clearer answer rather than "No comment"

EOSHD: Is it a Panasonic sensor? So it is not a Sony sensor?

Inoue: Ah no comment!

EOSHD: Because I noticed this is a standard four thirds sensor, because the GH2 had a multi-aspect ratio sensor. The GH3, does that have multi-aspect ratio sensor?

Inoue: This is a priority for imaging quality, our big priority is keeping that image sensor quality.
