Hopefully new AMEX cards will start coming out soon from banks that issue Visa/MC. Visa and MC had in their contracts with banks that you could not issue another card and still issue V/MC. The courts said last year that they cannot do this so the major banks can now issue AMEX and Discover cards along with V/MC.
I've only heard of the first bank to start with AMEX later this year (forget name, but it was a big one - saw in USA Today).
I wonder if Citi will have some and maybe offer an AMEX with AA. We'll have to wait and see.
