The latest expansion for Imperial Assault, Jabba's Realm, was recently released, along with a number of add on packs, that I am slowly making my way through. To start with is Luke Skywalker Jedi Knight and Shyla Varad, a Mandalorian, who is one of the expansions player characters. Though what is interesting, is that she is not a rebel, but part of the scum and villainy faction.
Jabba's Realm also introduces Jet Troopers and a new Imperial officer, Captain Terro on a Dewback. The Dewback kit is nice becasue you get two rider torsos, one Terro, and another regular trooper with a lance as seen in A New Hope, though as always with these kits, the lance is a bendy mess.
