I just ran across an offer I had not seen before on aa.com. 40K miles after spending $2k in 3 months, plus a $200 statement credit for AA purchases in the first 12 months, annual fee waived the first year. It does have the 24 month language, and it doesn't seem to have the 10% mileage rebate.
Not sure it is worth putting it in the wiki, somebody might have a use for it.
