especially since it's the final class and thus spent the most time in development
Quibble time! I'm not disagreeing with *anything* you wrote, but I think this one piece of logic is off - just because other classes were in EA doesn't mean at all that development on them stopped. I expect we'll see modifications from EA on literally every class
Oh, I agree (i.e. we know wildheart barbs are getting more forms for example), but we've already seen that the classes weren't done at the same time. We've seen stuff slowly come online like spells, mechanics (reactions), etc to replace placeholders, and they mostly fit with the classes they needed them. A lot of the stuff they saved for last no doubt required either homebrew (possibly--no hopefully--assassin) or unique work (spore druids), and since monk seems to be homebrewed far more heavily than ranger, it makes complete sense that they were the final class.
For the existing classes and subclasses, I honestly wouldn't expect much to change from the way it is now.
