Some developers discontinue or abandon older hardware when an upgrade is released, whereas the Axe FX II and AX8 will still be updated with algorithms that are shared with the Axe FX III, though undoubtedly the developers will have to make some compromises.
What about the FX8? I had literally bought mine used when Mark II came out and I lost equity, but I really dig it. Will FX8 Original be unsupported at a known point?
