Does anyone know if/when Anna and Elsa will be officially added to the Disney Princess lineup?

Fear not they WILL be added...Disney uses the coronation as a money booster, when the tangled hype died down, they coronated rapunzel to boost her merchandise for a while, the same happened with Merida but frozens doing extremely well STILL, despite a whole year later frozen merchandise is still flying off the shelves (even with the heightened prices) so most likely disney is just waiting for frozen to die down, and THEN use a coronation for a boost again
