I think part of the reason for the anticipation and excitement is all the goodies that sidefx mentioned during 19.5 launch event or surfaced separately over last year:
- D-box improvements as a central control
- more curve parametrization
- multi shot editing
- meshing tools improvements (hopefully the long time ago promised quad remesher)
- full on animation and dynamic rigging
- new frameworks and architectures?
- white water in sops
- art directable curves in crowds
- feathers and grooming improvements
- finished muscles
- new viewport based on Vulcan
- compositioning redone or at least started (sounds to me like the next great thing!)
- basic painting of attributes textures
- karma cpu enhancements and karma gpu out of beta
Those are the things I have noted. Doesn’t mean they will all be here and finished but h20 looks like a massive upgrade.
During 19.5 launch they had mentioned that next release would be early to mid 2023
