Ohhh hell yeah!!!
BD let this loose on IRC last night when the early rumours/reports were flying around but it has now been confirmed. This news ofc deserves a thread.
No Kenji Kamiyama or Yoko Kanno attached to this anime unfortunately but Kazuchika Kise (directing) worked as an animator on the GitS movies (and the Evangelion rebuilds too) and Tow Ubukata (writing) is behind the great Mardock Scramble.
At the time of writing this nowhere seems to state what the format of this new anime will be exactly, whether it's a movie, series or OVA. I'm thinking and hoping it'll be a series rather than movie but either way I'm sure many of you will be extremely excited to see a new anything of Ghost in the Shell. I know I certainly am.
