the retirement of the enterprise at the end of TUC ...
Captain's log, U.S.S. Enterprise, stardate 9529.1.
This is the final cruise of the Starship Enterprise under my command.
This ship and her history will shortly become the care of another crew.
It doesn't sound like the Enterprise is going to be retired at the end of TUC, rather Kirk is going to transfer command to another Captain, and then Kirk (and not the Enterprise) is going to retire.
