I doubt it to be honest. AOTC had many characters without figures. ROTJ already has many main characters in the HT line. Crossing out slave Leia and Han Solo, you're looking at reissues or version 2.0 for most.
Doubt it. Not right away anyways. With the bargain bin prices, I'm sure there are people buying some to sell in the future so the supply isn't really going down much.
