I don't think D&D will ever really change much. There are people that really like its quirks, and there'd be a backlash from people if they made large changes. People still repeat largely nonsense complaints about 4e, sometimes while trying to patch 5e with ideas that 4e did.

Unfortunately, some people like it without ever trying anything else. D&D is a mega behemoth. I personally think it's more popular than it should be, given how many people I've talked to that play it only with a generous heaping of house rules and practices that transform it into something else.
