I think Gruber is being extremely optimistic here. It is indeed very strange that Apple is shipping new iPads every year, each revision making iPadOS even more comically out of touch with the hardware on which it runs. I'm sure Apple is planning something but we could just as easily be waiting another 2 years before iPadOS takes advantage of hardware capabilities, since Apple does plan ahead but they never tell us what they're planning. iPad-buyers are clearly fine with the current state of iPadOS, and Apple is clearly happy with the number of iPad-buyers. They're in no rush.
