They did announce what they were going to do at the last L&L, but not in the order they were going to do it.
As BOB mentioned, Talion (pirate Mercenaries) are up next and they have a skull-carrying, dreadlock-sporting Warcaster announced for it.
Grymkin was last to bring their clockwork Chicken and a few other models in to the field.
Before that was Steelheads to bring their new artillery models in to play (along with several solos).
And before that, all I can remember is Skorne's Exalted (statue focused), but I think there was at least one between it and the Steelhead release.
