It does list all amex cards on one page now, backend is the same. But pretty usefull info on the new page, like which cards you have, the balances, the new charges, etc. I think they are going to update the website in phases, they problably just went live with phase 1.
Same here, also says gold optima. I never had a gold card, went from regular skymiles to optima platinum. I wouldn't worry too much.. -Roman
