A few days back it was reported
that Tecmo is planning to announce a new game on March 24th, that which would likely be a PS3 exclusive title.
Today, king zell
of NeoGAF (linked above) has spotted a Famitsu scan revealing that Tecmo's upcoming title is none other than Ninja Gaiden Sigma 2 for PS3.
Additionally, http://www.1up.com/do/newsStory?cId=3173295 has confirmed the news as well adding that the PS3 port will once again be directed by Yosuke Hayashi
There is no word yet as to whether this will be a PS3 exclusive or not, however, as first Sigma was released only on PS3 chances are good it may be.
