After that January 26 will come around when we see the first better-than-Hubble image of Ceres. Dawn will then approach Ceres, pass by it a bit, get captured in March, and turn back. Not sure what pictures we'll have around this time, but once we have anything better than Hubble the mission will be a success.
In any case, massive speculation about Ceres should begin in just 18 or so days. In the meantime New Horizons won't be at better than Hubble resolution for Pluto until May, so January to May will be Dawn's time to own the limelight.
