True the option of 4K is great, sure 6K could come in handy for certain work. But I would like a boost in film IQ, more like the Varicam. More DR, better highlight rolloff, less noise, better codec(prores,h265, raw). If 6K and 4k 60fps are the only selling points over the GH4. I will not be buying one, then I even choose the A7S ii over it. Why would you wait till photokina for such specs.
