The ERG and Ahsoka are great choices. Ackbar and Lando... I think it's good they're branching out again into secondary characters, because it seemed from the TFA offerings they were sticking to pretty much main characters / troops, but unless there's some tie in logic that comes to light later, they're odd choices. There are highly requested TVC characters that make much more sense in relation to Rogue One, so yeah. Odd. Glad to see the line rolling along.
