I wasn’t lucky enough to find the first wave of the Star Wars Black Series, but while these aren’t the figures I’m (currently) looking for, you can pre-order the second wave of figures now. Cases of Star Wars Black Series Wave 2 are up for pre-order at Entertainment Earth and BigBadToyStore for $79.99.
Since there’s no army-builder like the Sandtrooper in this wave, cases (which are evenly packed with one of each figure) may be the way to go. But if you want to order them individually, then BBTS has listings for Han, Leia, Greedo, and Boba Fett (although he is already pre-sold out.) Both venues list wave 2 as coming in November this year.
