Why is there no US release?

How does this show not have a US release? It a type of show like naruto,mar, or bleach, with more depth (those are all licensed). The creator of the manga already had a failry successful show in yu yu hakusho, hxh is infinitely better. The manga is licesned. It is a perfect length, gundamesqe. Its not to long like naruto bleach or one piece, so many people who tend to have shorter attention spans will watch the whole thing. And they still have ovas to continue the show. *sigh*
