XDA contributors claim to have found code in the latest version of the OnePlus camera app for new features that are likely to launch alongside the upcoming 9 flagship series.

I'm waiting for the OP9 Pro to replace my OP6. I travel extensively and if the camera is is not good enough (close to/as good as my digital camera), then I ill be abandoning OP altogether and going with S21.
