Dance Dance Evolution is good for video game software and online computer games, which narrows down speculation quite a bit. In addition to this trademark, we spotted Cross Board 7 also registered by Konami.
Update: Cross Board 7 and Dance Dance Evolution are the European names for Adrenaline Misfits and Dance Masters, respectively. Thanks for the sleuthing liamscanlan and James!
