If you scroll down more in the entries you can see the cover of newtype with Ganta and Shiro

In case no one but me noticed: Gantas voice is now listed on ANN.

FREAKING OUT WITH EXCITEMENT

Also noticed the station showing it only does more mature stuff. More excitement. Foaming at mouth I think.

According to Moon Phase Diary and this post at ASuki, Deadman Wonderland will be recieving an anime adaptation! Nothing on the studio or staff or cast yet, though my personal guess is that Bones will be animating it.
Exciting news~ though the anime was inevitable, ahah.
