What’s interesting though about Poe’s inclusion is the timeline. The Resistance was established by Leia I think about six years before TFA. But Poe only joined something like a year beforehand. So we’ll either see them stretching the limits of what they’ve previously established (I guess there aren’t any exact dates in the material related to Poe), or they’ll just set the show within a year of TFA, which is possible, but seems tricky. The other option would be to set it before Poe joined the Resistance, and when he shows up, he’s still with the New Republic, which could work.
It’ll be interesting to see what other characters they get to guest. Funnily enough, like TCW, this will be another “kids” show where we know most of the characters will wind up dead shortly after the show ends - that is of course unless they continue through TFA and TLJ.
