That's cause Rival Survival aired on TV, no? Something like that. Also it was special cause it was the first big graduation/change in the line-up for a long time (Sorry Koharu lol) and the first time in a very long time that they were at an arena. After that, that hasn't happened again. They did USB and Live-viewing in cinemas or something for Ultra Smart and Ai Believe, but those were also special as they were graduations.
For a "normal" tour such as this one? Pft, just gotta wait for the DVD 'til March (I guess). Maybe April if you wanna get the Blu-Ray.
