The coming attractions imply Major Beck is going to hammer Jake and the towns of both New Bern and Jericho because Goetz finally got what was coming to him.
Of course, Goetz had already been FIRED by Ravenwood (and their employer, J&R) for embezzling funds, so I don't know what the problem is here. And it's not clear why Jake & Jericho are going to be punished, since Beck found Goetz strung up at New Bern.
Maybe they need to come up with some reason to have a car chase with a nuke . . . time for "willing suspension of disbelief" again.
