I am also a Centurion card holder and have had an Amex card since 1978 without an instance of fraud.
I was travelling in Singapore, Malaysia, Thailand and Paris and was notified of a possible fraudulent usage, initially KFC in the USA for a couple of dollars, and then River island in London for a couple of hundred pounds. I travel almost constantly throughout the year and Amex picked up this fraudulent usage very quickly and handled sending the replacement card from Australia to NYC very efficiently. The only possible places I think the card could have been compromised was a large dental centre in Bangkok and a large chain pharmacy also in Bangkok. The only other usages were in high end hotels.
I will wait and see what happens with the new card.
