The airline does plan to keep the 777's and order more. They have 5 more due for arrival in the near future. They were unable to cancel these. The full pilot vote on the contract is to be finished by mid November. I guess they agreed to let the 777's fly until the end of November expecting the pilots to approve the $250/hr rate.
I do expect them to make a large order of 777's in the near future. However, I don't expect them to get rid of the MD-11's yet. I do wonder if they will order different versions of the 777.
