hi,
i was looking at this last week as well
here is the full article about it:
https://unofficialnetworks.com/2022/11/28/double-decker-snowboard/

in ISPO take on this, they say it benefits freestyle, carving and makes snowboard an easy entry for a beginner.
how it is possible that it benefits all these groups.
I am sure though it will be marketed as a revolutionary, completely new system to snowboarding, never seen before...
