I have heard that they will draw more! Just need to wait (If I am right last movie came 2013 summer and they draw pretty slow if you look at every episodes date..).
Well I enjoyed it. Sadly they are not keeping up, anime was not really popular (I have heard that in manga whole stuff are different, so thats may be the case).
I really recomend "Deadman Wonderland" for peoples who have enjoyed "Mirai Nikki"!
