Do you have concrete evidence of this idea of a 14.5 or is it purely speculative?
It has seemed like Harmony and Storyboard Pro upgrade patterns exist in separate universes. Not to say they do not work together but you would think each would receive all of the other’s advances in turn as they would apply to their unique purposes. This has not been consistently the case. SBP seems to receive more workflow advances while Harmony receives expanded functionality. SBP is more of a workflow tool anyway. Storyboarding is just storyboarding. Harmony being an animation system encompasses a wider range of upgrade possibilities.
Software companies have to ration advances. You don’t want to offer too much or too little. If you are on an annual major upgrade path, a full step major upgrade that is merely enhancements to workflow would be disappointing to many but a half step consisting of nothing but improvements to existing features would be welcomed as long as it was priced accordingly.
