They havent announced it but I have hard (and I aplogies if this has already been mentioned) that they have updated the pre dispatch show ready for FN and also added a few more actors in the ride.
I also wonder if the whole Fanta thing will be one of the bits hiding behind the leaves, I know they said this would only be for specific dates though so would't be the best idea.
I am with ItzAdam on that it will be more scare zones, stating that nowhere is safe is an over statement if the only two areas are the dome and near stealth.
