Talonbane Cobra is 28 points, PS 9, and has a great ability -- in my mind, he's fairly analogous to Wedge. Based on that, I would guess that FFG will price the generic at 20 or even 19 points, and I can see it getting a fair amount of use if that's the case (at least until Scum gets a better 20-some point ship). The options will be warthogs for 23 to 25 points, or the Khiraxz for 20(ish) -- I could definitely see people playing the Khiraxz under those conditions, since you're saving three to five points. If we get a 21 or even 22 point Scum ship with three attack dice, though, I would expect the Khiraxz to die off pretty quickly in favor of that (as the X-Wing died off to the B-Wing).
Well, a 19 point generic would see five of them with dampeners in a squad, so i'm thinking 20. Maybe 21 just to piss everyone off.
