First, let's break them down by movie:
Ep. 1 - PODRACERS, MTT
Ep. 2 - JEDI STARFIGHTER/SLAVE I, GUNSHIP
Ep. 4 - X-WING/TIE ADVANCED, Y-WING
Ep. 5 - AT-ST/SNOWSPEEDER, AT-AT, TIE FIGHTER, TIE BOMBER
Ep. 6 - MILLINNEUM FALCON
What other sets would others like to see? So far, the sets have been released in waves of four, two from the Prequels and two from the Original Trilogy, with the secret set being a ship from the OT.
What I think would be cool is a four-part Death Star with parts to configure it into the Death Star II!
