Dpreview.com recently posted an interview with Michiharu Uematsu and Yoshiyuki Inoue.
quote from article -
"They explain the challenges of making and marketing a high image quality compact and suggest the GH3 won't get focus peaking.
Uematsu spoke about how the market has reacted to the company's products: 'GH3 has been well recieved, especially for motion pictures. As you know we interviewed many people in the industry in Europe and North America, so it would offer what they needed - broadcasters needed bitrates above 50Mbps so we offer 50 and 72Mbps. In Europe they needed 25p, not 50i. And they're using GH3 - it's much smaller and lighter than a professional camcorder and doesn't need several people to operate it.'
However, he says, there is still one feature they're calling for. 'Focus peaking and zebra pattern. More than 90% of the requests we're getting are for these features. We haven't been able to offer it - because of the limits of resources and of the Venus Engine processor. Because it is not included in the Venus Engine, focus peaking is very hard to introduce - anything we added in software would be very different."
