I guess you don’t read DDMS
He clearly writes:
AMEX emailed me and let me know that as part of their new agreement, they will be offering a “new consumer premium Card” and “enhanced small business Card” next year.
And:
I’m excited to see what kind of premium Marriott/Starwood card that AMEX will be able to pull off. Best of all, as a new product, everyone will be eligible for the signup bonus!
"A new" implies one new personal card.
"Enhanced small business card" also implies one card.
No plural used anywhere in that statement.
Based on this language, if they offered 2 new SPG cards, there would be no new Marriott cards. I assume that they at least plan on introducing a Marriott personal card. The enhanced business card could be Marriott or SPG.
As I said, the language does not explicitly say that there will be new SPG cards.
