I agree with the previous speakers.
While in Paris, the studio is usually 6-8 cards made with the girls, the same American studios (except Anya case of his 6 card installed with her) the girls 2-4 cards they are doing, which would not be a problem if the remaining DB-card would appear. But this has not happened, in fact there has not been DB-card and before that only a few pieces on for months.
I know it has slowly become a mania, but really, why there are no new American DB-cards ... AND why it is not at least a few Duo cards - not in Paris, not in the US?
