From the update:
We have just added five bonus miniatures to our initial offering. This means that if we get funded we will produce nineteen miniatures instead of the fourteen that are planned now. If you have pledged any support level except Airship Deckhand or Airship Sailor, you will receive the extra five miniatures. That's right new miniatures without doing anything.
We are doing this in order to get more miniatures produced and available by making our funding goal. Please send this information along to your gamin friends so we can make our funding. Thanks for the support!
