Is anyone watching this on FFG Live? They've announced three paint sets for Star Wars: Legion!
Here's the link to the official article: https://www.fantasyflightgames.com/en/news/2019/5/9/bring-your-army-to-life/
A base Legion set and two add-on sets with extra specific colors for Rebels and Imperials.
The specifics are pretty thin at this point but it look obvious that the paints will be manufactured by Army Painter with FFG branding. They have the same dropper bottles and lid colors as the regular Army Painter line, and it looks like the same washes. I'm not sure if the actual paint colors are the same with different branding or if they are totally new colors.
Edit: Looks like the Legion Core paint set is 16 paints and 2 washes (plus two brushes) for $49.95. The Rebel set is 9 additional paint colors plus 1 duplicate wash color (Strong Tone), while the Imperial set is 8 additional paint colors, a varnish, and 1 duplicate wash color (Shadow), for $29.95 each. That seems generally in-line with what I would expect.
