Appears to me the stats, based upon other sources for the B-Wing and Slave I, should be about the same, so:
Attack = 3
Defense = 1, or possibly 2 (but I'm betting they'll rate it like the Y-Wing)
Hull = 6
Shields = 4, or possibly 5 (there are two ratings on-line, for the B-Wings shields, with 100 SBD, and 125 SBD, which correspond to the ratings provided, respectively)
I think the maneuver dial will be about the same as the Y-Wing, though possibly slightly faster than it, but with slightly less turning ability.
Can carry twice as many Proton Torps as the Y-Wing.
