The future seems to be in question.
For all the improvements that the 2024 version makes to D&D, it does also seem to have a lot of "unforced errors" which are keeping some players from moving over. Some people speculate that the current IP owners may just license the brand out, and stop printing the books themselves -- something that was almost unthinkable, within recent memory. But with the Warhammer IP seemingly being farmed out to whoever will pony up the cash, D&D might not be far off from heading in the same direction.
You also have to think of all the previous D&D authors, who either have already written their own systems, or are now working for competing companies. I think it's fair to say that being able to have the official D&D brand on your RPG system would increase the sales potential by an order of magnitude. Whether or not the price is right, is another matter.
But where does the game go, in terms of actual mechanics? The "feat + ASI" paradigm of 2024 seems popular, and advantage/disadvantage seems to have caught on (a departure from the earlier, wargame-ish stacking bonuses of 4e or 3.5) but tool proficiencies still seem like a mess, and the places where they were obviously going to overlap with skills...? I feel that's a problem that existed since 2014 with no real fix in sight.
The official virtual tabletop for D&D has been axed, as well. Alternatives exist, but I think this development sort of hints that D&D may still be a physical product, for longer than otherwise might have been predicted... or it might just indicate that there will be increased monetization, if there's ever going to be support for such a platform.
What's the next "big" thing in D&D? Do we see more crossovers (Magic: The Gathering, Rick & Morty...) or revival of more old settings? Is a space/future version of D&D in the offing, along the lines of Starfinder? I genuinely wonder if this formula for character advancement will last into another edition -- or do we see a split, like Essentials, where the game tries to break the current paradigm and forge its own path? For all the intricacies in the game, it does still feel very stripped down. In parts, it even feels bare-bones. It'll be interesting to see which parts of the game see the most effort and development, in the coming months and years.
