I would say, that you probably not helping to bring the updates live on FM3
If Fractal designates FM3 as a budget version, and you suddenly want a budget version over a higher-class version because it's better or the same, they might consider, that they are doing too much for FM3. (this is a joke... might be)
But I think Fractal does great work with every unit! I have FM3 and FM9. I clearly see, that I wouldn't use FM3 for live gigs. I might consider it with FC6. But it makes no sense then because it's the same size and almost the same price as FM9, but the firmware possibilities are drastically different.
But I see that FM3 is a great thing for bass players or guitarists who not changing scenes too often.
Why do I write this? Have no idea! I just want a gapless switch and trying to kill some time
