Japan not as nuts for the crimson/black DS Lite as we are?

We all know how nutty for the DS Lite Japan has been in the past, it would appear that Nintendo is finally starting to quench consumers' thirst in the region. As the new crimson/black DS Lite released to Japan last week, it appears that it failed to sell out at retail, a feat accomplished by many of its predecessors. Of course, this leads us to one question: is Nintendo finally catching up with the Japanese demand or is the crimson/black DS Lite just not appealing to consumers in the region?
