i cant see this card surviving if it has a credit limit like that. to a certain degree, the whole point of amex charge cards, and cards like world mc, visa sig/infinite and mc ultima is the spending limit vs credit limit.
amex wouldnt let citi issue a charge card would they?
The Chairman Card doesn't have a spending limit—it has a credit line that you can exceed in an Amex-like fashion. (Assuming Amex ever actually approves purchases over the hidden charge card limit, which is dubious. I've seen people post of being about to exceed their Citi line by at least 2x.)
But to actually answer your question, I just noticed that the Citi AAdvantage Amex card appears to work just like the other no preset limit Citi products such as the Chairman Card. So Citi could certainly re-brand it as an Amex without a preset limit, other than the "soft" limit of the revolving credit line.
I agree with the general consensus that it is unlikely to become an Amex though. I suspect that the current card will remain a World MasterCard and the new card will be a World Elite.
