Famed insider, VolckerC, posted this bit of information about Target 3-packs on the German Star Wars site Light Speed.com:

In addition to wave 1 of the three packs that we already know about, he listed that a second wave was coming, but did not reveal the contents (even when pressed), and further revealed that a third wave is being planned.

If Hasbro keeps releasing three packs that have vintage analogs, the contents should be easy to deduce.

VolckerC, who knew of the Rise of Boba Fett UBP in advance, also said that there is more TVC product to be revealed for this year.  Can’t wait for SDCC.

UPDATE: Click through for a breakdown of which vintage counterparts have been released and which ones could still provide a source for future 3-packs.
