Yeah, I also will base any pre-order on the inserts. As of now, I've only ordered one box from my local comic shop. The Facebook page vaguely described the inserts and I am cautiosly optimistic, but would love to get more specifics.
Cool Tom, I hadn't even realized there was a series 7 Facebook page. Here is the information about inserts that is posted there, sure makes me wonder:
There will be Wack-O-Mercials, Classics Foil cards, Cereal boxes, and other bonus cards. We will provide more info and perhaps some images as we get closer to release.
