Don't forget that we got a lot more than just the Target UBP sets.
2007 had more than a few large sets that were simply called "Battle Packs' - the Bantha, Treachery at Saleucami, Geonosis Arena, AT-RT Assault, etc. Lots of things were called "Battle Pack" but were more than just the basic 5-figure sets.
Sure, it might just turn out to be a box of Skiff Guard repaints but it isn't impossible that it is something larger or deluxe like some of the other stuff planned as BPs next year (like those Rancor sets).
