Well, I guess we know the answer to this question now.
You were right. Looking at the past two years I guess an iPad update will happen in March April time. The Mini could do with an update.
I think I might not get one though as I really need a new Mac, and my iPad Pro playing Resident Evil Village reminds me why I got it in the first place. The main issue I have is typing on it, maybe I'll look at the Apple keyboards?
