I missed this one by several days but I figure it’s worth mentioning anyways despite that. Konami is now testing the latest iteration of their Pop’n Music bemani series in Japan, Pop’n Music 18 Sengoku Retsuden. The subtitle refers to the warring states era that has been seen in many different games like Samurai Warriors and similar titles. A little more info can be found at BemaniStyle.com.
