Let's be realistic here. Why doesn't AUH want out of GF? Because Etihad does not have enough planes yet and cannot support the airport all by itself. GF has more than half the flights to AUH, and if they withdraw from GF, there will be no need to build the new airport anymore since GF can no longer have any international flights from that airport (other than to BAH and MCT). AUH will withdraw once it gets its 777's and other airbus orders. AUH cannot support 2 airlines together competing against each other.
