It looks like they'll be getting away from the traditional beginner,sport,expert,semi-pro, pro system and going to a more simplified system like the roadies have. Nothing is official yet other than a change will happen but for now the plan is to have Cats 4,3,2,1 and pro with age dividers among the cats. The age dividers will be broader than the current age ranges (i.e. 30-39 instead of 30-34). The Pro category will have very strictly enforced entry restrictions to try to increase it's level of competitiveness and international profile. Some discussions are here and a DH focused one here. I just hope the new system doesn't screw local pros, i.e. Bart who can hang with the big dogs but don't have time to hit all of the national races.
