Evidence of Sony censor?

Panasonic during their interview directly said ( http://www.imaging-resource.com/news/2012/09/28/qa-with-panasonic-the-story-behind-the-new-gh3-and-compact-system-tech)

1) "...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..."

does "our sensor group" from Panasonic sound like Sony Semiconductor ? do you think that Panasonic will call Semi Semiconductor "our sensor group"

2) "...Panasonic: We don't publish a specification for dynamic range, but yes, we increased the saturation electron number and also improved the signal-to-noise ratio..."

does "we increased...and...improved" from Panasonic sound like "we" = Sony Semiconductor ?

it is very simple - Panasonic was always designing 2 different sensors... both groups were improving, however it happened now that group that was designing smaller sensor (always intended to be sold to Olympus) was able to outperform the group that was designing a bigger one... GH3 could not wait any longer for a bigger sensor, decision was made to go w/ a smaller one which was already delivered to Olympus... nothing strange... Intel had competing groups designing different Pentium architectures for example.
