I have to admit, snowboard cross is exciting but then again I come from a motor racing background so I enjoy the race style of a event.
Slopestyle, Half-pipe or Big Air? Neah, not so much.
I mean Aerials was an Olympic event long before Big Air ever became a thing and it's like a totally Asian/ex-USSR event with some one-offs from Australia.
FIS is run by Norway and that won't change for a long, long time. They don't see the value of expanding the nations pool which is quite shallow by default due to snow being non-existent in half of the world.
