So I went into Walmart today and just like every time I do, I checked for new Galactic Heroes. The section hasn't been restocked for three months, and today it looked the same. When I got closer I discovered that they had only one each of the four new packs that I've seen advertised in recent comics:

Revenge of the Sith
Saesee Tiin & Agen Kolar
Commander Bly & Aayla Secura
Ki-Adi-Mundi & Commander Bacara
Tarfful & Commander Gree

Needless to say, they are awesome! According to Rebelscum.com, I have all of Waves 1 - 16, both Convertibles, and the Millenium Falcon.
