Doesn't look like the GH3 is getting peaking

No eventually it will all be controlled via an App on your Android or iPhone or Tablet while doing video. You can already do it this way for stills. However, focus pulling isn't really exciting for stills.

You won't have to worry about "Jabbing at the touch screen" or disturbing the camera. However, this won't happen with the GH3 because it can't do video and live view through wifi.

This will all appear in a later model. Probably the GH5(There won't be a GH4 because of the whole death thing). However, they are starting on it now instead of working on getting focus Peaking to work. When they get the AF to work in this manner while filming you won't need or want focus peaking anymore.
