Obviously no one can say for sure, but we've already got some of the major features down... 4k60, expanded dynamic range up to 30 fps, stereo sound etc.
I would say possible improvements include:
- HDR10+ recording modes
- expanded dynamic range up to 4k60
- better quality hfr options
I think it's been rumoured that the ultrawide lens may not have stabilization.
There's mostly only refinements coming I think, it's a period like 4s to 6 where we had mostly similar looking 1080p video from the iPhone.
Op, do you find the xs generation video lacking? It's one of the biggest jumps forward in video we've had with the iPhone.
