Well, given the most recent information, that is what was communicated by Kaplan and the rest of management at the annual meeting, they seem to have high hopes for both products, namely the watch ecosystem (Cura myCadian) and the motor (Aegis fluid power). Cura myCadian is further along because it's already commercialized, specifically they have orders already.
But ultimately, does it really matter what makes the company successful? Does it matter if it's one or the other or both products? Let's go further with this. For instance, can a short and distort manipulator (which I posit) claim legality in his actions because Isotorque didn't pan out? Would he only have done wrong if the company had succeeded with it? Is that the measure of justification?
