Lots of shounen ai manga were released by the several German publishers in December. Presents for the numerous yaoi fangirls in Germany? I would think so. Overall the number of manga is surprisingly low, however, some publishers will release their January novelties before Christmas. Therefore the amount of actual December releases will be far more than the average ~50/month.
