Citibank has just introduced an AAdvantage debit card. It's very similar to the Chase Continental debit card, in that it has two levels:
Basic: $25/yr., 1 AAdvantage mile/$2 spent, maximum of 60,000 miles/yr.
Premium: $65/yr, 1 AAdvantage mile/$1 spent, maximum of 100,000 miles/yr.
(For those keeping score, that's $5 less than Chase for the basic card and the same price as Chase's premium card. Citi doesn't offer some of the bennies that Chase does, such as President's Club passes.)
I haven't seen an official announcement, but product information is available on Citibank's online banking site:
