I’ve always wanted a Star Wars movie or show with a nonhuman protagonist, so I’d be down for a Bothan spies show.
We’ll almost certainly see this someday. When Matt Martin, member of the Lucasfilm Story Group, was once asked about Bothans.
It’s pretty easy to confirm: we are purposely trying not to show them to leave all possibilities for when that story gets told. The dude in Resistance is based on the EU design of a Bothan that the Animation art team used as reference for a background alien. It’ll will come out eventually. Maybe they’ll be just like the EU versions and that dude in Resistance has been a Bothan all along… but we won’t know until we know! For what it’s worth, I believe the first story appearance of a Bothan in the EU came about 7 years after they were mentioned in RotJ and that was in a novel with no visual representation.
That’s good enough for me. And, as we’ve seen before, it’s never a good idea to rush things.
