A first list of possible Canon EOS 6D Mark II specifications surfaced at Canon Rumors.
- announcement first half of 2017 (CP+?)
- 25MP sensor (with possible prototypes being around)
- tiltable screen
- dual SD card slots
- might have 4K
- less weight and smaller size
I think we can be pretty sure that the Canon EOS 6D Mark II (previous rumors) will also have Dual Pixel AF and an updated AF system. The articulating screen is also very likely. I do not think the EOS 6D Mark II will have Dual Pixel RAW (featured on the EOS 5D Mark IV).
