I find it hilarious that after the new Panasonic GH6 camera was already in stock in the UK, Panasonic Japan issued a statement that the GH6 may not be delivered on time because of the high demand. Today all Panasonic GH6 camera configurations are in stock everywhere in the US: Adorama, Amazon, and B&H Photo - I guess the demand was not that high after all.
Panasonic also released a new GH6 firmware update version 1.1 with a single fix:
When a RAW image shot in High Resolution mode was developed using RAW development software, there were cases where false color occurred in the developed image. This issue has been resolved.
Panasonic Japan: the GH6 “may not be delivered on the day of release”
