So here are my best guesses for some of the cards that have not been fully spoiled yet.

1. Selflessness

Unique

Small Ship Only. Rebel Only.

When another ship at Range 1(-2?) suffers an attack, you may discard this card to suffer all of the uncancelled Hit and Crit results instead of the target ship.

2. Br.. Specialist

Crew

When you are dealt a faceup damage card, you may discard 1 reinforce token to flip it facedown (without resolving its effect). At the end of the combat phase,... are dealt...card, flip it face up and resolve it.

I think this cards lets you delay the effects of a crit until the end of the combat phase, which is a hard counter to Kylo Ren if I'm right.

3. Cruise Missile

Missile

Action: Target Lock: Discard this card to perform this attack. You may reroll you attack dice equal to the speed of the maneuver you executed this turn (to a maximum of 3 dice)

4. Mine Map

System

During setup, during the "Place forces" step, you may place any number of Bomb Upgrades in play, corresponding to...the play and... of...

I think this lets you place bombs on the field during the Place forces step. Pretty crazy if that's what it does.

Anything I got wrong? Any insights into what I couldn't figure out. Please help!

Bomb(let) generator is seemingly the only bomb slot option for the 'heavy bomber' and there are two seismic shaped tokens in the package. It's unique so my guess is reusable 'seismic charge' dropper which costs 2x bomb slots and drops 2 tokens at once using the 1 banks.
