The ladies of SNSD have had an exceptionally busy year with their Japanese debut riding alongside their Korean promotions. Yet it's all paid off - their popularity has exploded to new heights both at home and abroad, and it's certainly looking like it won't reach its apex any time soon. On December 3rd, an article covering SNSD's success in Japan was posted on Billboard's news site. While fans are sure to feel proud of their girls, they'll also feel ecstatic in reading that there's plans of releasing a full Japanese album, "due in the spring". Arguably though, the best gem in the article lies in the rumor about SNSD's possible expansion into Europe for 2011. No word yet from SM Entertainment about the rumor, so stay tuned to allkpop for updates! In the meantime, be sure to check out the Billboard article here. Source: Billboard News Tip: Yumii
