I think that's mostly true, at least in principle. I suppose the one caveat would be that I feel like there's been more grumblings from older fans over the last five years or so, in the post-Tasha's world. I don't know if it is because Dragonlance, Spelljammer, and Planescape were all considered somewhat disappointing (not by all, but certainly by many), or if there was a tonal shift (maybe both, and other factors). But on paper, there's still a nice range of products, and I think the formula of 1 splat, 1-2 settings, 1 adventure anthology, and 1 story arc is a good one.
