The timing of this announcement is unexpected, and interesting. I mean, we all knew that Filoni's team was working on something - and that it was likely called "Star Wars: Resistance", based on Disney's trademark filings.
But...why not wait until after the Solo movie has been out for some time before announcing it? Why risk any distraction from that? Even announcing it a month after 'Solo' comes out, it'd still be half a year or more before the series airs.
Odd.
(Although it does make me wonder...do ya suppose FFG might have anything to announce about this next Tuesday, now that it's out in the open?)
