New trooper 2 pack is possible, plus obviously the officer. Those troopers and the all important blue guy are likely the only characters from episode 6 specifically I predict will get figures. Still, 3-4 figures from one episode alone is a good amount.
Previous episode offered a greater number of potential figures: 2-3 versions of that popular PT guy (4 if you count the helmeted look seen briefly), 2-3 versions of the main lead Ahsoka, reg troopers phase 1 and 2, 501st troopers phase 1 and 2, 332nd phase 2 and Rex phase 1 and 2 all being possible choices for HT to pump out.
All those plus the early episode options (Baylan, Shin, Marrok, Hera, Chopper, Huyang and the already announced Sabine plus maybe long hair Sabine) will make for a vast figure line should HT decide to start going deep.
If HT go the more conservative route (stupid move IMHO given the fan response and toyetic nature of the characters), I think the announced Sabine may also be acompanied by Ahsoka the white, Baylan and new officer trooper. Possibly Marrok, Shin and basic trooper too.
Whatever route HT go, they are gonna see many figure sales given the more positive response to the show (Kenobi and BOBF managed to sell figures even with the negativity so this show should have no issues).
