Just saw this article online: www.digitalcameraworld.com/news/panasonics-first-mft-camera-with-phase-detect-autofocus-coming-soon
It refers back to an M4/3 Rumors website article about a possible G7 Mark II and I guess this fits with Panasonic's recent statement that it still thinks there is a market for compact cameras.
I'd rather see a rangefinder style body, i.e. a GX7 Mark IV, which would probably be called a GX9 Mark II or a GX10 outside of Japan. I think that would be really cool.
