Scum, preferably more than one faction of them.
However I think it pretty likely we will all have our wishes granted, or at least most of them. It seems part of what has hurt X-wing is over saturation of models for each faction. For example the rebels have six ships with one agility and eight-nine total health.
It seems like additional factions is a better way to keep new content coming and develop new game mechanics while warding off some of the power creep that has harmed X-wings game play.
