We run Guant, Colm, Rawn and Mkol in that order for the ones I posted, and we also have Larkan and Try Again Brag in the set. No word on when its coming or how much, but these are the first previews I'm hyped enough for I'm pretty much guranteed to order.
I would LOVE to see a full squad, and I think its interesting that this could actually be a legal set. A commissar, command officer and 4 person command squad. Perhaps if it sells well (which I think has gotta be nearly guaranteed right?) that they'll expand to some of the other fan favorite characters. I've seen them say before in interviews that they're looking for ways to make realistic female models and Gaunts Ghosts has a bunch of possible options there.
