The comments you have been making lead me to believe you think that Cliff could have an FM9 that has all of the Axe III's functionality and could release it but chooses not to. If you're meaning that he may have one he's developing, that's completely different and a clarification like that would solve a lot of the misunderstanding here.
You are absolutely entitled to your opinion. However, people like Greg have a bit more knowledge of how FAS works so his opinion has more credibility IMO.
True, each device is geared to a different market and as such have different processors and memory capabilities that dictate what can and can't be done with each device. To have an opinion that Fractal purposely keeps features out of reach on the FM3 and FM9 is simply unsubstantiated.
If you followed the release of the FM3 and FM9, you would know that Cliff packed everything he could into them. He even considered two amp blocks for the FM3 but discovered it would reduce the quality of the tone too much. How the devices sound is much more important to him than functionality or features.
Everything I've read that has been posted by Cliff, as well as other developers, has shown time and time again that they are committed to getting the most out of each platform. Going back to the launch of the Axe III and the Ares modeling platform. Fractal had zero obligation to port any of Ares to the Axe II or AX8 but they did. People wanted and expected more, but it either wasn't possible or would likely require taking more resources away from developing the Axe III which is an unreasonable expectation of any business.
