Starwood Business
It seems that if you're on the web page that displays all the Amex Business cards, clicking on the "Offer Terms" link for the SPG Business shows the old "12 month" language. However, once you click on the apply button, the new language shows up on both the application page and the "Offer Terms" link on the application page.
I had been holding off on re-applying for this card, so this got me concerned. I sent myself a SPG business card referral from my wife's account hoping that I would get lucky. Success! The referral application link shows the "12 month" language. I better go ahead and apply before it gets taken away, too.
