I dont know what A9 II has to offer in near future, current A9 is more than what I can dream for
It is very difficult to predict , bayer sensor technology almost reached theoretical/technological limit for image quality. Possibly we could expect advances in sensor data processing , maybe global shutter as well.
There is still a lot of things on the way.
I would be interested to see following with the next a9, a9r, a9s.
1. Increase in well capacity so that more photons could be accumilated - for any brand, not only for Sony
This is easier with BSI technology.
2. Implementation of old Sony patent for electronically switched pixel color filters - with that no need for pixel shift to get full sensor resolution, no moire, ability to shoot ful res. monochrome images at any selected light spectrum range. This also could slightly increase sensitivity for red and blue channels.
3. Higher analog DR range - possibly using dual pixel or combining dual shots . There is interesting piece of information regarding new HDR mode on recently announced new Sony medium format sensors, somehow nobody noticed and mentioned that so far. Though no information how this is implemented. The only thing that they compress it into 14 bit possibly using kind of HLG. Not using yet 16bit ADC. This what we will see soon on next deneration of medium format camaras. Hopefully we will see the same on Sony a9r.
4. Have 16 bit ADC if #3 is implemented. Posibly have option to switch between 14 and 16 bit modes.
5. Have losless RAW compression using latest compression technologies, e.g. based on wavelets transforms or methods used in h.265 for video.
6. Have HLG is standard option not only for video but also for still - seems that a7r3 already have that.
7. Have 10bit 4:2:2 internal video recording.
8. Have option for DNG output.
9. Internal timelapse.
10. Internal image focus stacking as on Phase One camera.
11. High ISO improvements, at least 0.5 stops , though seems that it could be difficult to acheive.
12. Night mode - low light sensitivity increase one or two stops using photons multiplication technologies as used in some science sensors, possibly never happen but it is nice to dream about that.
13. Super fast super high resolution GM prime - I would like to see 35mm F1.0 GM AF prime. This would be perfect for night street photography, maybe for astrography as well.
14. And last but not the least - further improvements in AF capabilities , especially fo "Lock on AF mode", which requires icrease in processing power and some pieces of AI technology implementation.
