These are out. I saw all 6 today at a Target. $24.99 each. They don't seem that bad in person, just that they used the older molds for clones and the sandtrooper, which weren't bad molds.
Battle Droid is the Arena 2-pack mold but with the officer antenna, not the backpack.
Dooku is the Arena 2-pack version...I think.
Han in trenchcoat uses the Endor battle pack head.
Not sure which Vader it is, Evolutions mold...but not sure which removable helmet style it is.
