New Amex Platinum Metal Cards Already Delayed

Yesterday, the updated benefits for the Platinum Card from American Express went live. One of the new features is the new metal card design shown below.

I have no urgent need for a metal version of the card, but I like having new shiny things. So, early yesterday morning, I decided to order a replacement card using the “Card Services” section of my online account. All seemed well at the time. I had two shipping options–both free: USPS standard mail or UPS overnight. Obviously I chose UPS overnight.

This evening, when my card hadn’t been delivered yet, I logged onto my American Express account and noticed the following banner:

The date in my delivery status still shows 3/31. Clearly, that isn’t going to happen. I don’t know if American Express ran out of metal cards, or just couldn’t handle the number of requests. What did they think was going to happen?
