Don't know what country you're in, but we struggle even to get full HD here in Aus a lot of the time, let alone 4K content. 8K? Don't make me laughDoes anyone have the bandwidth and monitor resolution to take advantage of 8k Netflix? And is there really any point? I have a 1920x1080 40” TV and standard HD Netflix is excellent on it. What would 8k, or even 4k, add that is worth all the extra cost?
Anyway, if it does happen in the GH6, I have a hard time seeing Panasonic abandoning their current market. I'd suspect we'd see something like the current lineup, of the GH5 & 5s, where 20MP would become the new 12.
