I've been hearing that Inuyasha is going to have a second series and continue where they left off from the manga (since the maga is finished) and that they are going to get the old voice actors back together.

Inuyasha's Final Chapters Get TV Anime Green-Lit (Updated)
This year's 34th issue of Shogakukan's Weekly Shonen Sunday magazine will announce next Wednesday that an Inuyasha Kanketsu-hen (Inuyasha Final Chapter) television adaptation of Rumiko Takahashi's manga has been green-lit. The anime will broadcast on Japan's YTV this fall and cover the story in volumes 36 to 56 of the manga — the final 21 compiled book volumes. The original staff and cast will reunite for the new anime adaptation.
Shonen Sunday had promised earlier this month that it will be including a special news announcement about Inuyasha in issue #34. Takahashi had ended the Inuyasha manga in the same magazine last June. She has been serializing a new manga called RIN-NE (Kyōkai no Rinne) in the magazine as well as on TheRumicWorld.com website for North America readers since April 22. Viz Media has been releasing the Inuyasha manga in North America, and it has also released the original 2000-2004 television anime adaptation.
