I thought i should post this here since the new ip can be multiplatform.
"At GDC, Gamasutra had the chance to speak to Team Ninja's Yosuke Hayashi, and he revealed the pressure the studio is under to live up to its legacy after the departure of its leader, Tomonobu Itagaki -- as well as revealing that the developer is working on multiple projects, including new IP. Tecmo and its studio Team Ninja recently announced Ninja Gaiden Sigma 2, a PlayStation 3 expanded remake of last year's Ninja Gaiden II, which was originally published for the Xbox 360 by Microsoft. The new version, which ships this fall, will include new playable characters, online co-op play, and other improvements."
