Loser at the 'Pursuit of Happiness Contest'
If I remember the KS - messages right there will be 2 shippings for us KS backers.
First batch: For those who ordered only the base game.
Second batch: For those "all in" or with various expansions.
Where the retailers fall in I don't exactly know. Might be they come after the first batch shipped to KS - might be that Mantic tries to ship to KS first (which most of the backers would appreciate).
For some reasons most KS I was in ended up in retail before backers got their stuff. That usually causes some frustration but in the end everyone has their stuff and it's fine.
