I was thinking about the likelihood that we'll see certain characters again in the future or if a given character is one-and-done and not to be released again. As someone who is not a completist, I'm happy if I get at least some version of the major Star Wars characters in my collection at some point. Based on past SW collectible games and the FFG SWLCG, here are my thoughts on Awakenings:
Admiral Ackbar: I feel like he's mostly one and done. There's a chance that we'll see a ST version if he does more than just direct the battlefield.
Bala-Tik: Definitely one and done.
Captain Phasma: Very likely we'll see alternate versions of her as long as she's in the ST.
Count Dooku: I really think one and done. Granted WOTC released AOTC and ROTS versions of Dooku in their TCG and minis games, but I don't think there's enough differences to warrant another version.
Darth Vader: We'll definitely see alternate versions of Vader in the future. His pic shows his shoulder armor above his robes, which makes me think this is an ESB/ROTJ version.
Finn: Very likely we'll see future versions as long as he's in the ST.
FO Stormtrooper: Likely we'll see alternate versions like the Riot Trooper, but the base Stormtrooper is one and done.
General Grievous: He only appears in one movie and this version seems to sum him up nicely. One and done.
General Veers: This version is pretty complete - one and done.
Han Solo: This Smuggler/ANH version is one and done. He's really good and I don't think he'll even get an obligatory power creep revisit in the future. Still, expect alternate versions like General Solo for Red.
Hired Gun: One and done.
Jabba: Very likely one and done. There aren't really alternate versions to work with.
Jango Fett: One and done. He's also too good for a power creep revisit.
Kylo Ren: Definitely will see future versions as long as he's in the ST.
Leia Organa: This Hoth version is one and done, but we can expect ANH and ROTJ versions.
Luke Skywalker: This Knight version is one and done, but I can definitely see him appear in a starter set or a more older Knight version from the ST.
Nightsister: One and done.
Padawan: Very likely one and done. They could make alternate versions of generic Padawans, but I don't think that's likely.
Padme Amidala: I definitely feel like we'll see an AOTC for Red.
Poe Dameron: We'll definitely see alternate versions as long as he's in the ST.
Qui-Gon: One and done. Unless he comes back as a force ghost in the ST.
Rebel Trooper: Same as the FO Stormie.
Rey: Definitely will see future versions of her, probably as a Legendary next time and maybe again as a starter set in a few years.
Tusken Raider: Same as the FO Stormie.
