Quote from Mierten
Volume 15 came out in January 2010 so I don't think this is discontinued.
Except Viz very own site shows this:
There are only 14 volumes, from what I understand volume 15 was put up by some online retailers for per-orders but Viz decided to stop at volume 14 as the phrase "Final Volume!" seems rather conclusive about it.
What part of "Please do not put in huge images!" did you fail to understand?
