I became a SPG Luxury Amex cardholder on January 22, 2019. 75,000 point bonus if I spend 3k in 3 months. I'm just now seeing that the SPG Luxury AMEX will be renamed Marriott Bonvoy Brilliant and come February 14th will have a 100,000 point sign on bonus.

I'm a little irked I am going to miss out on the extra 25,000 sign on points because I signed up for the card a few weeks too early. Do you AMEX will give me the new higher bonus to me? Not sure what they've done in the past with situations like this. I just talked to AMEX via online chat and they said they don't have info yet on the exact changes and couldn't comment.
