From The Force Guide:
“TFG: So for the Black Series 6”, a lot of the prequel characters and Clone Wars characters have been great additions, like Qui-Gon and Captain Rex. Will we be seeing more of those prequel and Clone Wars characters going forward?
[Hasbro Star Wars design director Steve Evans] : Yeah. 2019 is 20 years of The Phantom Menace. We’ve been talking about it a lot, actually, at this convention. The love for the prequels has kind of gone through this sort of—hate has kind of gone into, like, love again. There’s a lot of memes out there, and Hayden Christensen had a good response when he made an appearance, I think it was at Celebration. We’re seeing a little bit of love coming back for the prequels, so we’ll share some love on that, I’m sure, going forward.”
