A small correction first. We reported earlier there would be a HX400 successor. The source corrected the info because the camera will replace the HX300 and not the HX400.
So far he heard of three cameras going to be announced soon by Sony:
Sony A6100 E-mount APS-C
Sony HX350 fixed lens compact
Sony HX80 fixed lens compact
Still no 100% reliable info about the “high End” stuff. But stay tuned…
