They seem to be avoiding releasing it on DVD and Blu-Ray because of fear of reverse importation of at least the Blu-Ray releases but also the DVD ones. Viz will end up selling InuYasha: The Final Act here for far cheaper than it will be in Japan.
They also surely want it on TV here before they roll out the home video release because that serves as an advertisement for the home video release.
Viz had to wait until the dub was done over at Ocean Studios in Canada and there seems to have been some complications.
And lastly after so long of a wait Adult Swim doesn't seem interested. Despite running IY every Saturday at 5:30AM because they still have a contract for it, they may have no intention of finishing the series so long after the fact.
I'm sure it would still do plenty well if they did air it but maybe Viz wants a lot of money for it and they'd rather buy something cheaper since anime is a low priority for them these days.
HELPeR for the TOONAMI, Mobile Suit Gundam, Dragon Ball Z, Harvey Birdman and Perfect Hair Forever boards. Feel free to ask me anything on those topics.
