Last of the Continentals?

Since the United-Continental merger was announced in May, 2010, there has been a gradual shift from the Continental name. For most of the intervening time, we've had Continental aircraft showing up more and more frequently with the United name on the side, but still using the Continental callsign. Meanwhile, United aircraft have been appearing with the new hybrid livery: Continental paint scheme with United lettering. As of the first of December, Continental no longer exists as a separate air carrier. I talked to my last Continental flight on the 28th of November; when I came in a few days later, the transition was complete and all flights were using the United callsign. Except that a few Continental aircraft have yet to be re-lettered; I caught this B738 about a week later. Will it be the last?
