I honestly think that in the next 10 years, as long as manufactures are will to comply, and produce actual entry level gear at a entry level price, this tiny little nitch sport could consume up to 10% of the snowboarding market. I think this sport can only go up from here. Not because we're at a all time low, but because there is so much or a resurgence in carving, and people trying to make their own mark in the snowboarding world.
Last year, at my small local hill i met 3 alpine guys, who showed up there regularly. This year i've met at least 7 guy, maybe more, who ride alpine.
I'm just going to sit back and watch this sport grow
