The action figures below are .... Caprica Six, Head Six, Apollo, Helo, Anders, Chief Tyrol and Brendan "Hot Dog" Costanza.
And why isn't the Chief Tyrol action figure available for pre-order? *cry*. I heard a rumour that it's going to be a San Diego Comic Con Exclusive. Damnit, I'm not going to SDCC this year, I'll be in Vancouver instead :( Hopefully it will show up on ebay.
EDIT: If you would like to pre-order the figures (as a set or individually) here is the link for the BigBadToyStore website http://www.bigbadtoystore.com/bbts/menu.aspx?menu=227&category=421 I'm sure there's other places you can order them from, this is just one suggestion.
EDIT: Edited again to add the image for the Chief Tyrol Action Figure.
EDIT (May 31st): Added image for the Brendan "Hot Dog" Costanza Action Figure.
EDIT (June 8th): The Chief Tyrol Action Figure is available to pre-order from the Diamond Select Toys & Collectibles website. Unfortunately you can only pre-order it if you live in the USA.
