Any future TV series could contradict the RPG/novels, but not the other way around. Therefore the secondary canon has a temporary canon status (ie canon until such time it is contradicted), and hence it cannot be considered to have the same canon status at the primary canon.

As time passes the primary and secondary conons will diverge. It has happened to many other TV and flim franchises. Star Trek for instance has multiple layers of canon that contradict each other, and even have contradictions within themselves.

Don't get me wrong, I have no problem with extra canon, and I do consider them to be true canon. But it is for this reason that secondary canon should always be marked as such, so that people recognise that there is a possibilty its canonicity could change at a future date.
