i am pretty sure almost every member on the site would LOVE to see JOSS come back for one huge reason: they do not pay for it.
i miss JOSS dearly as well, however i believe jon takes big losses out of his own pockets for the competition, as do the athletes (somebody has to pay for transportation/accommodation). combine that with the fact that athletes were being assholes to jon (team america releasing their video prematurely) and shitty weather threatening the entire competition, and it's not hard to see why jon just doesn't want to take on the project anymore.
hopefully he'll find it in him to put on another few JOSSs. produces some of the best skiing with the best coverage.
