A new anime series based on Sailor Moon will be released in the summer of 2013, according to Anime News Network.  The new series will be released simultaneously worldwide.  The theme song will be performed by Momoiro Clover Z.
Despite its age, the Sailor Moon manga has been tearing up the charts here in the U.S. since its re-launch by Kodansha last year (see "Top 25 Manga Properties-2011"); a new anime series, especially if it’s broadcast on TV, can only fuel greater awareness and sales.
