i went to the adobe production studio tour. it was very informative and detailed the new features not only in ae 7.0, but pp 2.0 and audition 2.0.
all i can say is WOW! i can't wait to get the production studio! real-time color correction, direct link to other applications (no need to render, export, import (and vice-versa) if you're in 1 app and need to edit in another app).
