To clear this up,
There is no such thing as "demonstration" "showcase" or "exibition" events in the Olympics anymore. They have not done that since 1994 in Lillehammer, Norway.
Think about it for a second, was there ever a snowboarding "demonstation event"? No, it was accepted for Nagano and was an official medal event right from the start. Was snowboardcross an "exibition sport" in Salt Lake? No, but it is a medal event in Torino.
That is how it works now, you are either in or out.
If the ski industry (especially sponsors) and athletes start supporting a World Cup circuit, then FIS will probably be able to get pipe in the Olympics.
