If I recall correctly, Cliff once said that If he incorporated more of those elements (Color/touch display, USB audio, scribble strips, headphone jack, etc...) the AX8 would be much more expensive. It's not valid to say that Helix, Headrush, even the new Hotone's & Mooer's pedalboards they all have all or most of those elements as comparison, remember the AX8 has much more expensive audio components and cuts had to be made in order to keep a competitive price, prioritizing audio quality.
Honestly, I don't think the general consumer target for Fractal is more on 'looks' and 'how modern the package is' as much as is into how better it sounds apart from the other modellers (neither are IMO the guys from the Kemper camp, the thing is absolutely fugly but I recognize it sounds awesome), of course the new FC's looks amazing but if having all the bells and whistles means putting the next generation AX right next to AXE FX III in terms of price, well, then I'd rather get the III.
