Hi Nick, KS exclusives will never be made available to retail. They are Runa and all her components (montage cards, solo mission etc) as well as 8 upgrade tiles.
Rosari will be available in retail. Saboteurs, Meatboy, Dens will only be available in limited quantities in the US from Greenbrier and whatever shops they will distribute these items to (not sure yet) and from the Mighty Boards site.
Thanks grinn. I made a purchase on gamepledge.com - thanks!
Is mid-oct the expected ship date?
