1080 60p, headphone jack, and focus-peaking are deal-breakers, in my opinion. They simply must be there.
From there we can talk about the codec. If they don't want to go 4K so as not to cannibalize the cinema line, they have to give us at least 100mb/s. That's still only half of what the GH4 will be providing.
As for low-light and moire/aliasing - 7D mark II will need to best the GH4.
I'm comparing to the GH4 because from all indications, the two cameras will be in the same class and price point.
