I'm not sure why you posted those links. One seller has only 21 reviews, I'd never buy from them. But if the price of the GH5 and GH5s drop, that's cool by me.
I realize the focus is on Panasonic, but theoretically, this should also affect Sony, Canon, Olympus, Fuji and the rest. All this speculation about the demise of Panasonic is hurting my poor brain.
