Well there's a blast from the past. How's it goin' Matt?
I think someone posted an early general wave lineup somewhere, a while back (w/o specific figures), and it totaled about 24 or so at the initial Ep. 3 release. Maybe someone else can confirm that a little better though.
From the JD.com news front page:
The JediDefender Spy Network has reported in with a sneak preview at what may be arriving for the Hasbro launch of Revenge of the Sith!
It appears that spring 2005 will see a return to the Collection 1 / Collection 2 separation of the basic figure line for Episode 3. Collection 1 will once again showcase the main characters (Ani, Obi-Wan, Padme, Palptine, Mace, Yoda) with Action Features, while Collection 2 focuses on the secondary characters (along with a few main characters) and posability.
Currently, there are plans at Hasbro for about 17 unique Collection 1 figures and 12 unique Collection 2 figures are in the works for the launch of Episode 3 (expect another Midnight Madness party at TRU as well).
There are plans for 2 or 3 different case assortments that include the 17 Collection 1 figures and at least 2 different case assortments of the 12 Collection 2 figures.
The hard-working staff here at JediDefender bring you the news as soon as we hear it, but please realize that with Hasbro, as always, everything is subject to change.
