New ef game by Minori soon?

[img_assist|nid=1001483|desc=|link=node|align=right|width=130|height=95]Minori posted a quite interesting image on their website. Looking at it, some well known characters from Ef can be identified like Miyako, Nagi or Chihiro. However there seem to be at least two new characters. Are we looking forward to a rerelease of Ef with more content, similar to Shuffle Essence? We'll know on February 10th.
