The size of company might or might not matter.
The resources (and attention) put by a company into a particular product is what matters.
Falcon is probably more important to UVI than Halion is to Steinberg.
Halion's development has been at a standstill for years, which shows that Steinberg is not willing to put resorces into it (for whatever reason).
If a new Halion version shows up it'll be years late already, even with nice features like FM etc. And it'll be a paid upgrade and followed by another decade of non-development.
This is the complete opposite of how UVI treats Falcon.
