Based on what we just saw with Imperial Veterans, I think the probability of adding Integrated Astro to Rebel Veterans to be very high.
To mirror Imp Vets, and assuming it's an X-E Wing fix I think we'll see something like:
PS 6 Generic Rogue Squadrons X Wings w/ EPT, priced in the 24-25 range
Corran Horn & Tycho Celchu for X Wings, priced in the 26-29 range
PS 5 Generic Wraith Squadron E Wings w/ EPT, priced in the 30-31 range
PS 4 & 7 unique pilots, one might allow X Wing only cards
Two copies of Integrated Astro
4 Titles available to X Wings and E Wings both
A new unique Astro at the 2 point mark, maybe making torpedoes more attractive
Two copies of a generic Astro for 1 point, to improve their jousting efficiency
2x A new sensor upgrade specific to E Wings, to help the generics/low PS pilots
Cool Hand
Plasma Torpedoes
Wild guessing, but I bet we end up with something along these lines.
