New info (robbed from FFG
First off Aces packs are making a come back (probably to replace reprints).
Spoiled: Resistance aces pack will be the first pack and it will have a bright orange x-wing
"Familiar ships with new paint jobs"
More thematic to time period or event, or media that comes out (hence the Resistance pack with an orange X-wing being first)
Rebel cells, imperial battle groups, etc
"Hefty on upgrades"
Good for starting a new faction or getting into the game
They are revisiting iconic pilots at different stages of their lives
New subtitle, new ability, potentially new initiative
And some spoiled cards;
