Panasonic pushed a ton of features to the G9 (my current top-end camera) that make it very competitive with the GH5 for video, so they seem to have gotten some religion on that front. Five year old cameras are likely past the cliff of "too slow "for a lot of feature improvement, though. I have a GH3, a G7, and a GH4, and they all have the same sensor but even the UI on the GH3 runs slower and chunkier. Trying to wedge more stuff into it seems like a bad time.
