IAW has listed 6 background costumes to go along with the Alamo model they listed earlier in the week. I think this is pretty telling. Martin probably didn't want the Alamo model because of its size, and he has enough background costumes so that he didn't take those.
I will not be surprised if this is all we have to look forward to....Martin's rejects! :-)
Time shall tell, but I don't think we will see any interesting costumes or props in the future. IAW is just cleaning out Martin's leftovers.
