It's a full year away so who can say what about it, but I am far less concerned about what the 2024 Monster Manual does than the PHB. I've been fixing 2014 D&D monsters for ten years and still enjoying the game but when stuff hits the player side, it takes a lot more work to socialize fixing it (if one ever really does).
By the time the 2024 Monster Manual comes out, we'll have so many core monster books – A5e, 2014 D&D, and Tales of the Valiant all will have core monsters in it and Flee Mortals has a lot of comparable monsters even if they aren't at the same CR or a perfect match. The cool bit is that we can use whichever flavor of monster we prefer to use. Want simple monsters that use the more modern spellcasting flavor? Use Tales of the Valiant (for a sample, check out the Black Flag reference document). Want more tactical monsters that work together? Use Flee Mortals. Want better balanced monsters that include spells and update the 2014 monsters? Use A5e (my personal favorite right now). Want to build your own monsters on the fly? Use Forge of Foes (ahem).
I'm interested in the Monster Manual but I'm far less concerned about it being perfectly right than I am the PHB. There are so many monsters and ways to build and modify monsters that I think things will be fine even if they're not perfect.
Now if they completely dork with the CR system, changing monster power outside of current bounds, and thus making all previous monsters incompatible, that would be terrible but I don't expect that to be the case. It hurts them as much as it hurts everyone else.
