I just received an e-mail from Amazon that my physical Imperial edition wont be delivered until April 8th. This with the 2 day shipping. Just a heads up for anyone else that ordered through Amazon.

With same day delivery I get it on the 7th

My worry is the grace period. If less than 5 days then alot of players will be out of game for a day or two while waiting for delivery.

I thought about that, but with the beta client being upgraded to the release client.. and we already entered in the early access pass. The actual physical box is not needed to start. Correct me if I am wrong.

Correct, with the codes we already entered we will start playing in the early access and will have all our bonus items and features. Can assume there will be a week or more grace period to enter the retail code. Might even be more seeing as the game comes with the first 30 days free.

I'm in the same boat. And grace period is only 48h.
