Quite frankly... I would have bought a new 5E24 Player's Handbook even if it only included Ranger buffs, 4 Elements buffs, some re-balanced or fixed spells like True Strike and Barkskin, and if they tossed out the individual species write-ups for the Half-Elf and Half-Orc and replaced the with a Mixed Heritage entry. I'd drop my money on it without issue.
When WotC announced when they were going to make a new trio of books for 2024 all those months ago... the calculation from that point was you needing to save $7 a month to be able to be able to buy all 3 when they got released (and if we add in the book price increase it's now like probably $8). And I easily determined I was good with saving $7 a month for however many months it was going to be to buy these books no matter what changes were or were not made to them. So if it turns out WotC only makes a handful of changes all told, but those changes fix things that people have been railing about for the past 9 years... then that's a good purchase as far as I'm concerned.
