i dont think progressing will ever end, in the next couple years i could see doing two grabs in the same trick happening alot, like mute to double nose or something. and if skis change enough we could see alot of huge tail/nose presses, like wayyyyy out, or like pollards nose butter on the box on lines site. i can see tight pants being the cool thing in a couple years.
all this i could see happening in only the next five years. but in like 15 there is no way to tell, i bet parks are gonna be the coolest thing ever in like 15 years though, like skatpark style stuff everywhere, and shit i cant explain.
its cool thinking in like 15 years ill only be like 32 and still skiing and getting better.
but eventually its gonna slow down alot, like snowboarding and skateboarding, like skateboarding 10 years ago wasnt much different at all, but its still changing a little bit.
i could also see flatland type stuff being huge, like doing a bunch of huge butters and spins out and stuff. and oh yeah, i bet poles might be gone in like 5, for park atleast.
