Ninja Gaiden Sigma on PS3
An enigmatic new Ninja Gaiden game has appeared in the pages of Japanese magazine Famitsu. Subtitled Sigma, the only things known about it are that Tecmo is developing it for the PS3, and that players will at some point have control of series character Rachel. SPOnG reasons that this is not a genuine sequel to the Xbox game but rather a PS3 equivalent to Ninja Gaiden Black, which simply added content to the Xbox title. Tecmo has gone on record as saying that for the forseeable future, the 360 is Team Ninja's priority platform. UPDATE: 1UP seems to confirm the info about Sigma.
