As has been posted before:
MY01 RS has no major changes.
MY02 RS arriving summer of 01 will be the new body and Turbo/SC
The MY02 will be on the car show circuit next spring. (just like the MY01 Forester and H6 outbacks were this year) When I asked subaru rep, that is what he told me. So just sit back and relax til you see one in your dealer with a turbo in it.
