So I finished unboxing 4 boxes just now, a few things I can confirm with reasonable assumption:
As mentioned earlier in this topic, each booster box contains exactly 12 Rares ® and 4 Super Rares (SR)
Among these 16 cards, you are guaranteed that exactly 1 of these cards will be a + card. This means that on average your odds are to pull an SR+ card in one of every 4 booster boxes or 1:64 booster packs. It's probably worth a mention that since the odds seem to be fixed per booster box, you could theoretically have + card hunters who stumble upon the + card early in their pack openings for a box, then sell off the rest of the unopened single booster packs...probably worth considering if you are out on the auctions buying up loose single booster packs!
+ cards come in two varieties: gold font, and gold font with a signature. there are both rare and super rare + types of both varieties.
If anyone cares to know the + cards of my haul:
Robin (F) R+ (gold font and signed)
Lon'qu R+ (gold font)
Catria R+ (gold font)
Marth SR+ (!!) (gold font and signed)
good luck card hunters.
