If you think the op9 isn't at least half way through the development phase... You'd be wrong.
I feel the same as the article writer that it's about time OnePlus produced a small/compact flagship. I've been asking for that for years, although I'm yet to see if OS11 makes their larger phones any easier to use.
A flat display is a must, but I've no interest in "wireless" charging and IP ratings. These days, I expect smartphones to be built with a reasonable amount of water resistance. If I want to use my phone underwater I'd expect to look for a special case.
