Just a random thought... This was posted before Seoul, Singapore, and Jakarta were announced:

"L'Arc-en-Ciel 2012 WORlD TOUR, including Hong Kong, Bangkok, Shanghai, Taipei, New York, London, Paris and other seven cities, and thus the rainbow after the first time in concert received media access from around the world, including Taiwan, France, Britain, Thailand, the media came for interviews, which in an interview with Taiwan record company Sony Music's visit, members have come to Taiwan for the first time four years ago left behind a deep impression."

So "other seven cities" might mean they are adding 7 more cities to the list. If Singapore, Seoul, and Jakarta have been just added, they have to announce 4 more cities right? Perhaps they will hit up Chile, Brazil, Mexico, and Los Angles? :O

This, of course, excludes Hawaii because it's not on the current World Tour list.
