9mm pulleys, idlers needed on latest genration shipping now?

I did a search but still am not sure. Does the xcarve that is shipping currently already set up for 9mm belts or do the pulleys and idlers still need to be changed out?

For 9mm 2GT belt, the idlers and belt clips need to be replaced.

For 9mm 3GT belt, the idlers, pulleys, and belt clips all need to be replaced.
