I remember 読書 that there was going to be a Season 2 of Another. I forgot where the 情報源 was, but the poster 発言しました they received that information from the 作者 of Another's Twitter account*. Supposedly, the new season is supposed to take place in this year, 2015(?) I believe.
*Note: The information from Season 2 of Another may または may not be accurate.
