> some new characters for the next S4 competition

Unfortunately judge by the time, for now it's in the middle of the second year and it's soon near the end, it's imposible to introduce new idols. In theory, the story should had noted some newcomers ever since the beginning of the year (except transferees like Alice). Now with that all fresh girls are only background characters, most current discussion consider that BANDAI doesn't really focus on the next S4 competition.

Of course what you say could still happen in the third year, but leaving the second year almost blank seems not be a very good and realistic arrangement for the plot.
