We have not run out of the first edition yet, but will likely run out sometime next year... we absolutely plan to move it into the new packaging on the next print run, but that won't happen until we run out and/or need to print more of the original Chrononauts... and we *might* let EAC be out of print for a little while in between depending on the exact timing of things.
So.... maybe 2012, more likely 2013? That's the best answer I can give you at this point!
Here's something for you and Andy to let simmer in your brains:
This year starts the 150th anniversary of the Civil War. Maybe a new edition of EAC could also come out with an expansion that adds more cards focusing on the Civil War. Or maybe Andy could come out with some whole new game with such a theme.
Sorry to see that we missed that anniversary. But don't fret! This year is the 150th anniversary of the Gettysburg Address. (I know because I was married on the 125th anniversary and it's our 25th anniversary this year!) Even an expansion pack with Civil War cards [i.e. Gettysburg Address as an Artifact] might fit the bill.
EAC is still on our slate for the very end of this year!
