The ORD-SEA 777 should stay in service since it continues on to NRT, same with the SEA-DEN-ORD 777 (which is the return from NRT). If UA decides to cancel SEA-NRT for DEN-NRT (I'd be surprised, as SEA-NRT makes money and I can't see many O&D pax at DEN for non-stop NRT service) then yes, we'd probably just get 757 service with a 763 during the summer and holidays.
