I think we’ll see two units in the new “floor” line. Both based on Axe FX III modeling and tech.
One more of an all-in-one processor with foot controls the size of the AX8. This one would aim for the Axe FX 2 in functionality and processing but with Ares tech (2 amps/cabs, most FX blocks from the III, headphone out, USB audio).
The smaller unit would be more compact. 3-4 buttons, less DSP. Probably less functionality than the bigger bro too, but plenty enough to replace an average guitar/pedalboard rig. It needs basic on-board editing, otherwise I doubt many people would buy it.
Both would be compatible/expandable with the FC6/FC12.
