As expected, here's my cynical and pessimistic prediction:
1. Battle Pack 1 ships to retail in a case by itself. These sell moderately well, and retailers reorder the next case in twice the amount they ordered the first.
2. Battle Packs 2 and 3 ship to retail in a case that also includes another Battle Pack 1. After initial sales to carded/boxed completists, the Battle Packs begin to sit.
3. Battle Pack 4 (the Hoth pack) ships to retail in a case that also includes more of Battle Pack 3 (the OT one, which will be the worst selling one of the initial three, IMO), and due to the lackluster figure selection of the Hoth set, and the increasing glut of the OT set, the fourth case assortment never makes it to retail.
4. Hasbro cancels the fifth Battle Pack (the one that everyone wants out of the five anyway; once again, Hasbro wastes the best for last) citing lack of retail support and/or collector interest, and three years from now, they finally release the 501st Clone as a single carded figure in the regular action figure line.
I hope that doesn't happen, but I'm not going to touch the first four Battle Packs with a ten foot pole (damn you Lisa and your restraining order! I shall burn an effigy of you with the school bullies!), and the fifth is the only one that I'm at all interested in. Naturally, it will be the most difficult to find of them all.
