You think 90% of everyone here is going to just stop using the 2014 books and only talk about the new ones? Nowhere near that percentage has even said they're going to buy the new books.
When the 2024 books come out, I will stop using the 2014 rules, and only talk about the current official rules.
Whenever an official errata comes out, I use the errata, and no longer refer to the obsolete text. I use Xanathars rules for tool proficiency, and Tashas rules for Personalizing Spells. And so on. I normally look up monsters online, so whatever DnDBeyond has for the monster stats that I am looking up, is what I refer to.
Unless I am specifically referring to something that exists elsewhere in D&D tradition − like 1e Drow Elf stats with low Charisma versus 3e Drow Elf stats with high Charisma, or 1e Wood Elf with high Strength versus 3e Elf without Strength, or 3e Sun Elf stats that lack Dexterity improvement while 4e Sun Elf has full Charisma improvement, or what the traditions say about the flavors of the Githyanki (psionic? necromantic? arcane-martial gish? how does all this make sense?), or the universal 4e mechanic of a power format, or so on − why would I be referring to a text that is no longer current?
I assume everyone who is keeping current with the D&D game will use the current rules, unless importing a variant rule.
Heh, plus, 5e 2024 might be the last time Core rules are published by means of the destruction of trees, and become a collectors item similar to the rarity of ivory.
