Talk out of Portland, Maine's Animaine is that Sentai Filmworks' upcoming anime releases include Mawaru Penguindrum, Ninja Scroll and Letter Bee season one. DVD and Blu-ray of Penguindrum and Ninja Scroll are planned for December, while Letter Bee will be released on subtitled-only DVD.
Penguindrum sees the return of the baroque directing of Revolutionary Girl Utena's Kunihiko Ikuhara on a well regarded magical girl anime.
Cult anime movie Ninja Scroll has recently been released on Blu-ray in Japan and will be coming out from Manga UK on November 27th. The specifics of how Sentai's release will compare are not currently known.
Tegami Bachi aka Letter Bee adapts Hiroyuki Asada's Shonen Jump/Jump Square manga, which has been released in North America by Viz.
