In the end, I plan not to buy the new edition because: I don't need it.
Funny; when I was younger, I was hungry for lots of crunch and bored with lack of options. Now having lots of options bore me out to sleep and find myself hungry for tighter designs. From what I've seen, D&D 2024's attempted to re-balance a lot of things by adding more, and the other attempts at re-balancing leave me rather lukewarm.
So I find that I don't care much for the race/species changes, don't care much for the class/subclass changes, and don't care much for the weapon trait specialties either. IMO, it was mostly the spells and feats that needed a re-balance (heck, i even think the '14's ranger was fine) and needed to be cut by 10% each. Now it looks like there's even more Feats and more Spells rather than less. If anything needed to be added, it would have been extending on the exploration pillar, so probably more a DMG thing than a PHB thing.
Ultimately, it's the new spell section that will make it or break it for me. We'll see if there's enough good in there to be worth the change but so far I'm not terribly impressed.
[edit] I should rephrase the last bit; the 5e2024 is impressive. The amount of work and thoughts involved is impressive. It may not be what I wished but i cannot deny the apparent quality of the product that is 5e2024.
