The official Twitter account for Food Wars! Shokugeki no Soma revealed that season will continue into the “Totsuki Ressha” (“Totsuki Train”) arc, which is part of the series’ larger “Promotion Exams Arc.”
The newest arc is intense, you can highlight for brief spoilers to get a peak of the action: [The first year students travel to Hokkaido for their promotion exams, but the students that opposed Central are given handicaps that set them up for failure. To make life challenging, the students are split up into different trains, with the “rebellious” students forced into shokugeki with the Elite Ten so they can take their exams.]
