With Line 6 and Headrush coming out initially with these HUGE way too BIG & HEAVY floor units with attached expression pedals and now are coming out with these tiny stomp units that are completely dysfunctional live, I'm hoping with any new model floor unit that replaces the AX8, that the physical size and weight stay pretty much the same. It's actually the perfect blend of having enough switches on the unit to be functional but small and light enough to fit easily into any backpack. I really fear that FA with make any new unit have a much bigger screen, which is fine as long as it doesn't affect the unit's overall size (just get rid of the navigation button and control knobs and replace with a touch screen). I'd hate to see happen what happened to the rack version - making it much bigger than the previous version.
