The last Sony a6500 model was announced back in October 2016 and the Sony a6300 was announced in February 2016. The model before that (Sony a5100) was announced in August 2014 (the Sony a6000 was introduced in February 2014). If Sony keeps that release pattern, a new APS-C mirrorless camera (or two) is expected to be announced in 2018. As it has been the case for the past few years, reliable Sony rumors are really hard to come across, but there are some references online about a potential new Sony a6700 model with the following specs:
- Better AF, like accuracy and sensitivity
- 1/8000s shutter
- Faster fps rate
- Flash sync 1/250s
- Improved silent electronic shutter
- A better stabilizer
- Two memory card slots, with UHS-II support (at least one)
- Raw-2-jpeg processing in camera
- Double exposure
- Built-in Wi-Fi
- Faster startup time, overall faster performance
- Adjustable touchscreen LCD screen
- Improved IBIS
- Built-in intervalometer
- Announcement in 2018
Needless to say that you should take this (and any other) Sony rumors with a grain of salt:
