In our case, we're growing via adoption of our first generation core product. I could definitely make a second version, but it wouldn't help overcome the primary challenge we face with adoption, which is that the technology looks unconventional, and isn't well-enough known yet. Making a more complicated version wouldn't help with this, and might not even improve the efficacy. It would also require internationalization, whereas our current version is language agnostic.

So it's not that we won't ever create a newer version, just that it's not the primary focus.
