To half-answer a question, the Prem Econ offerings from AA were announced. However the particulars regarding mileage accrual rates, eqp earning, mileage redemption for PY travel, SWU use from Y to PY or J, etc. were not announced yet.
Additionally, AA RDM accrual is changing later in 2016 to a cost of fare based system, versus the current miles flown + class of service bonus + elite level bonus.
If you can get a status match from AA for your CX status, it could help with boosting your earn rate on these longer (and more expensive) flights.
There are a few wiki's and stickies on the new AA mile earning program already done up for your reading pleasure.
