Hight School of the DEAD!!!

I just re-watch this anime, after the 1st time it came out. I forgot the whole story. When the fk are they going to continue this one??? I been waiting for the longest time.

This was all heard second hand but something like the original manga author had something that was keeping him from continuing the story but once he was able to work on it again, his artist had already moved on to working on another manga. And I thought the two of them were family or friends or something so it kinda turned into a feud.
