I got this from a source:
I have it from a good source that Panasonic is seriously looking at a S35 or Full Frame Video and Stills camera with internal 4K Raw recording and Live streaming with Integrated Apps for photo and video sharing to platforms such as Facebook, Twitter, Instagram etc….
The internal Raw recording will be in 4K but the video sharing will be a 4K compressed codec with different 8bit and 10bit 4:2:2 recording options also available.
One of the apps designed for the camera will allow limited video and photo editing before sharing (similar to an iPhone)
These camera/s will have IBIS and AF / face tracking similar to Canons Dual Pixel AF, and contain inbuilt ND’s. The cameras will also have large articulating touchscreen with a built in audio adaptor.
The source says one or two different version of the cameras are being considered, with modular add ons such as adjustable handgrip, moveable viewfinder etc…
He says to think of a cross between the current Blackmagic 4K Pocket Camera and a Canon XC15 with audio adaptor.
The are set to be announced around NAB 2019
