This bit of news was confirmed by Jinsei Kataoka and Kazuma Kondou. Entering it's final story arc, Deadman Wonderland was released in 5 volumes and appeared regularly in Monthly Shonen Ace till it took a hiatus and returned January 2013 in time to tie up lose ends and plot points and enter the final arc.
Deadman Wonderland also spawned a 12-episode series chronicling the first arc. It's got tremendous potential (so good that the www.thefanboyseo.com version 1 even had a good review on the anime series) and I was really hoping that it would be picked up into an ongoing but that looks like a farcry now.
