So I wandered over into the Persona community thread only to see that I'm not the only person who has received this email.

This is because this item contains regulated materials classified as dangerous goods and can not be delivered by Amazon. Although the amount of these substances in these products is usually quite limited, these products need to be transported in a certain way to ensure that they are handled with care.
Unfortunately, this means that we're not able to ship your order and it has been canceled.
We’re sorry for any inconvenience and hope to see you again soon.
It looks like Amazon is cancelling both regular steelbook and the "Take Your Heart" Premium Edition.
I sent Amazon an email, but LiquidGabx talked to an Amazon rep and posted their response...
So I'm wondering if 100% of the PS4 orders are going to be cancelled? What is the defect, and how does this change the launch date? Do we have people from Atlus or Amazon here on the boards that want to comment?

MOD EDIT -
My Bestbuy Take Your Heart edition got cancelled.
Update: My order from Bestbuy was fixed. Apparently some system issue and not related to the "Amazon" incident. Thank jeebus.
They specify Amazon, so I'm thinking it's specific to them.
