Surprised this thread continues with such gusto! The game can't be over; one team hasn't even shown up yet.
For me, the Axe Fx as a floor pedal already exists in the form of the Axe Fx and a floor pedal (MFC, LF, whatever). A cable to connect them isn't all that much extra effort. I even recall seeing a pedalboard here some time back that mounted the Axe Fx into the pedalboard. It can be done now, if that's what you want or need.
The AX8, as has been said many times (including by Cliff Chase), is not intended as a replacement for, or fully featured alternative to, the Axe Fx. It's a stripped down version with all the amps/cabs/effects/routing most players need to gig, at an aggressive price point. If it sounds as good as I expect it to, it will have accomplished its mission exactly. I'm not saying they'll never make a full-Axe-Fx-in-a-monstrously-large-all-in-one-box-pedalboard-format, but that's not what this one is about.
The only "GAME OVER" I want to see is the waiting game!
