I believe that the rest of the MXZ's (non REV X and Sport) will be in the ZX-X (last years "X" package) chassis this year. I thought I saw that the Trail and Adren. models will still be in the older chassis. Monday, Ski-doo's web-site will show all of the models for 2003. So we will know the answer then.
P.S. Sled_Dog, that Skippy comment really hurts!!!
