What do you expect to see in the GH5?

[Mat Mayer]

The 1080p crop seems to be full width in the M43 sensor, so that is 12MP from a 16MP camera. Which is three quarters. So best case senario is that the 4K crop will be 3/4 of 18MP which is 13.5MP. Then downsampled or however they do it? I don't understand why they didnt go full width for Cinematic 4k in the GH4, but I assume they will go full width if they can. They seem to of gone a bit wider with UHD in the G7, so if they continue with that maybe Cinematic 4K goes to the edges in the GH5 to get close to that 13.5MP?
