I think platform design is gonna plateau for a decade or so. Sure someone might find a way to make em a little lighter or grippier but I can't see anything truly revolutionary. At the end of the day, a platform is just a surface to put your feet on.
Not to get off topic, but I would really like to see some saddle innovation. For example, a saddle that let's you face away from the tree while sitting. Get the bridge behind you so you can sit in the same position you would in a traditional treestand.
I want to be able to sit in my saddle with my back tight to the tree sometimes to blend in with the tree a little better. Yeah, it's nice to hide behind the tree but deer don't always come from the direction you expect them to.
I also used to like resting my gun or bow sideways on my lap while I sat back in my treestand days. You didn't have to make very much movement for a stromg or weak side shot, even while sitting, just raise your weapon, square up, aim and shoot. You could do the same thing but in the comfort of a saddle if you could find a way to get the bridge behind you. Or better yet, have a 360-degree bridge, somehow.
