Infinite Heroes Battle For Metropolis

Forgot to post this earlier but apparently the Battle For Metropolis Infinite Heroes set is up for pre-order at Toys R Us. $50, plus shipping and handling for Superman (of Earth II... that's the gray haired one for those that only know him from Infinite Crisis), Captain Atom, Captain Marvel, Lex Luthor in battle suit, and 4 Luthor Troops. 8 figures, including the huge Luthor and the instant army is great, but 3 3-packs will only set you back $33 to $39 depending on where you get them. While Lex is huge, shouldn't the mass-production factor of just shoving a bunch of generic soldiers requiring no additional tooling bring down the cost?
