There were 8 statements, but there wasn't a statement that hinted at "Beasts." However, "Beasts" was one of the codenames we had already listed from casting. It's BY (Buttercup Yellow). The casting list (copied from Rumors):
CP = Carnation Pink
LG = Lime Green
CB = Cornflower Blue
LP = Lilac Purple
SO = Sherbert Orange
BY = Buttercup Yellow
DG = ? (forgot what this was)
Z = zones
So, I think that means there could be 9 groups total, or there is confusion somewhere along the line with how clues matched up with actual casting.
