User blog comment:Animefan0/Is Togashi Yoshihiro going do the manga for HXH 2011/@comment-48285-20121208165944

Togashi doesn't do any "OVA"s. That's up to the studios and television stations. How long the 2011 series lasts depends on them, not Togashi. (Also, in terms of the first OVA from he 1999 series, it's over as of this episode not started.) There also won't be a manga based on the 2011 anime series, as the 2011 anime series is based on the manga. And Togashi is set to return sometime soon, as he normally returns after specific volume releases.
