Panasonic registered two new cameras in Asia on March 8th: P2302A and P2304A. Both new models support 5.1/2.4G wireless and are expected to be full-frame.
So far, Panasonic has three registered but not yet announced cameras - P2303A, P2302A, and P2304A. The three new cameras could be: Panasonic GH7, Panasonic S1 replacement, and possibly a new Panasonic compact full-frame mirrorless camera with L-mount (see mockup above).
