Upcoming EP: High School

I hope, it isn't University 2.0. I like the concept but I have no idea what they can include there. After school activities? Teacher career? And what is more important. Will it be inspired by US high shool system? European? Japaniese? This is also important thing because we have a lot of different system around the world. I would like to see more school types than a single one. Public and private at least. In a perfect world, every world should have its own school.
