The Adventurer's Guide has 11 martial traditions in it. At 15 maneuvers per tradition, that's already 165 maneuvers.
Martial Artistry is going to have 12 martial traditions in it. Another 180.
The 2024 PHB has "Almost 400" spells in it. Between these two books we're going to have almost as many combat maneuvers... plus the GPG also has Beast Unity, Comedic Jabs, Dueling Maneuvers, and Gallant Heart for another 60 maneuvers.
So... Y'know. There's about to be as many combat maneuvers in publication for A5e as there are D&D24 Spells.
