My video are pretty normal and so I am going G9 for the 60 fps 4k and 180 fps 1080P. But if I did a lot of wedding, documentary, or music videos I think a camera such as the rumored Gh5s with a set of very fast primes (PL or Oly PRO) would make this a pretty special camera if it also has 4K 4:2:2 10 bit.
