They said today at the earliest. Here's hoping!...
Just in case anyone is watching and wondering... the ship arrived, and on Friday (2 days ago) the games were delivered to, well, I assume it's a warehouse or office? Maybe just somebody's home? Wherever Elzra is located.
Anyway, the point being that North American backer rewards will start shipping before long!
(With 2000+ backers, there is still a lot of work for Elzra to do and any individual reward package might still take time to be sent depending where your name falls on that list - and that's before even considering standard mail delivery times. But stay patient: it won't be much longer.)
