That PlayStation Move thing you have won't just be used for dancing and getting fit. Team Ninja and Tecmo Koei have confirmed that hardcore hack-n-slasher Ninja Gaiden 3 will also be fully supporting the peripheral.
Yosuke Hayashi, head of Team Ninja, does an excellent job of making the thought of using motion control sound totally badass. "Ninja Gaiden 3 is all about slicing and chopping through flesh and bone and PlayStation Move bring players even closer to the game's protagonist Ryu Hayabusa."
Flesh and bone! Visceral. Can't see granny getting involved with this one any time soon. As you're probably already aware, the press release notes that this is the first time the Ninja Gaiden series has adopted motion controls, so hopefully the studio is going to take its time in getting the implementation just right.
