I got this news quite a long time ago (I think over a year now...) from people who have been keeping up with the information that the people of Inuyasha are going to continue with the series, but weren't sure whether it'd be in OVA, movie, or another string of episodes format. This would happen though when Takahashi is done with the manga.
If you ask me for the proof, well, I can't give you that. Like I said, it was some ways back.
