Yeah, 8in/8out would be nice - if they put a solid, HQ converter in there - because really I could ditch another box. The X offers this robust IO, and if I didn't so strongly dislike their DAW I'd still have my pre-order for that on the books. It just makes sense to simplify the setup. The MK3 IO is awesome for live portability, but I do wish the unit had a 2 or 4 port USB hub and a phono ground on the back - to again remove little things from the setup (USB hub, phono preamp/z2). I have a Clarett 8in/8out thunderbolt interface and it's slick, but if I didn't need it, that's another $400 and one less thing to fail/glitch/update.
