First I hope the following feedback is not taken in the wrong way - it is of course for selfish reasons I write this, and I do not know exactly what goes on behind the scenes, so maybe you're already way ahead of me - but anyway, I think that at least partially Interaxon's goals might align with mine, so here goes:
If I were Interaxon, I would put new features in Calm on the backburner for now (bug fixes, whenever necessary, should still be high priority, of course).
Instead, I would work on the following three things:
Creating a learning app that allows the user to record their own brain states and use those as commands for BCI purposes.
Developing templates for a number of basic mind/emotional states (we now have 'mellow' and 'concentration', but are they actually useful for app developers?) I was very hopeful when I saw the Neuromage developer in the forum, intent on supporting Muse in his game. Looked like Interaxon did try to help, but eventually, things did not pan out. Super-important then, I would think, to follow up and ask him and yourselves why it did not, and fix whatever needs to be fixed, for that game and for any future ones.
Actively courting every provider of services that could interface with Muse to make them support it. Obvious candidates would be those apps and services that already support Neurosky and Emotiv.
I'm not an app or game developer, but if I were, the above would probably be high on my list.
Having developed a great piece of hardware is not enough... Now that competitors are moving forward, it is important to not get left behind...
