Yeah, I've also been having the thought that 2024 edition vs. 2014 5E resembles the 1E to 2E shift. The proliferation of settings is part of that (we know at least three more are planned as we head towards 2024), but also the emphasis on making the settings part of an interconnected multiverse. Not to mention the tonal shifts in the wake of both mass popularity and criticism of certain content, and the resultant changes with an eye towards growing mass appeal. Heck, they even brought back setting-specific Monstrous Compendiums! (Complete with 2E-styled cover art.)
