Salomon learned a lot from that time they made touring boots with tech inserts in it that didnt work/breaked/sucked.
With Greg Hill on their team it is safe to say they are working on a tech style binding but they will take plenty of time to develop something good. They did that with the Guardian, but to be honest I am not impressed with that binding. (Only for DIN sole boots, the climbing riser thing sucks, overal usability of the hike/ride switch and riser)
But I wouldnt be surprised if they have some working protos by now.
It will be interesting to see what direction they will go, something like that new Fritschi Diamir? A model to fight Dynafits Beast? Maybe a whole new system?
