The GH5mII was a stop gap to bring over some easy improvements from their newer cameras without a redesign, but these improvements could not be done without updating the processor. One being auto focus. From the company's internal engineering perspective it made sense but to most customers it wasn't well received.
Does anyone know if they have set a date for the GH6? In a May review they said it would be released this year but it's already November.
I do not think it was a stop gap. It was an updated model just like cars are updated almost every year. Some really nice features for me. USB power for long shoots, internal AND simultaneous external 10bit recording nice red border for recording just like my GH5S now. Just too much difference to trade my GH5. For others the streaming is a very unique feature to them in the way they have done it. With the new firmware it can also now just fit into their other model ranges for multicam streaming. Just because it does not have wonderful continuous autofocus at 24P does not mean it will not appeal to a lot of people. As far as I can tell from some of the tests autofocus at 60P is good. Not all the world is fixated on 24P. I for one never shoot other than 60P. If you are going to show in the cinema then 24P is fine but for PC, TV etc 30 is a better slow frame rate anyway and you can get that from 60P AND get your continuous autofocus better I expect from all cameras.
