Deadman Wonderland

Is anybody else reading this manga or watching the anime. Its pretty cool so far in my opinion but seems to be heading towards its end.

I've read the first 4 volumes of it at Barnes and Noble. good series, but I can't recall what chapter vol. 4 ended at and I'm torn between waiting for vol. 5 to come and just reading the series online (once I find out what the next chapter is).
