It won't be in store before September, but until then, the current series is still in store, so you can go hunt for the Warrior Woman minifig (also known as Ersatz Xena)

(By the way, the minifigures are in opaque grab bag, but if you look at the picture of the figure beforehand, it is easy to find the one you want by feeling the bag until you can make out the hairpiece or an accessory. All you need is time)
