<UPDATE: Tecmo-Koei has confirmed that Razor's Edge will be coming to the Xbox 360 and PlayStation 3 on the 5th April.>
Siliconera is reporting that the rumor that the Wii U exclusive Ninja Gaiden 3: Razor's Edge will be ported to the Xbox 360 and PlayStation 3 is true.
The Razor's Edge edition of Ninja Gaiden 3 includes new exclusive weapons, improved AI, and new enemy types and battle areas. The "Karma Counter" from previous games was restored, as well as adding online cooperative gameplay mode and Ayane as a playable character.
Ninja Gaiden 3: Razor's Edge sold 20K copies globally since its launch in November 2012, which may explain the decision to end exclusivity.
