i think now that hmd has partnered with Zeiss and nokia they will collaborate on exciting camera technology in phones to come ! :D
Microsoft are sadly still in possession of both the PureView and the ClearBlack IP, so we'll probably not see either of them. But I doubt Nokia Technologies have been twiddling their thumbs for the past couple of years, so let's hope they bring out something even better! We need a proper camera flagship in the smartphone space!
Ah, I assumed MS would keep PureView but it's a shame they're still holding ClearBlack as well. (PureMotion too?). I hope Nokia Tech/HMD/Foxconn/ZEISS can come up with something truly world-leading for the Nokia 9.
