Tecmo hasn't said much about Ninja Gaiden III outside of a cryptic teaser trailer and some obscure hints from the producer. Tomonobu Itagaki, the man behind Ninja Gaiden, Ninja Gaiden Black, and Ninja Gaiden II is gone – in his place is Yousuke Hayashi, the game director of Ninja Gaiden Sigma and Ninja Gaiden Sigma II for the PS3.
I really hope they're wrong. This would be just another unpleasent cosmetic feature (like purple essence instead of blood) that would ruin the game for me. It's stupid as it is cosmetic - I know - but I can't help it but feeling that way. If violence will be punished with demon corruption, I'll stay away from this, as I did with sigma 2.
