I REALLY don't wish for any new model of the Helix to come out right now since it's only been out for around two years and still being upgraded with new effects, amps and stuff. But I believe it would be beyond awesome if a helix unit could supply power to pedals like TC Electronic did with the G-system. The helix is FAR better than that if you ask me but still, If the helix is designed to co-work with other pedals on a pedalboard then let's make it all the way :)
I tried many gear pieces and I really don't believe that there's ANY floor based guitar processor better than the Helix right now. I believe Line 6 should put up a fight to keep it on that spot. :D :D :D
