You may not have been overly excited to see Nintendo unveil the Wii Vitality Sensor, a Wii Remote add-on that monitors one's pulse and "the body's inner world," but it filled No More Heroes: Desperate Struggle director Goichi Suda with ideas.
Sadly, those ideas don't seem like they'll make it into the follow up to Wii adventure No More Heroes. And the Grasshopper Manufacturer CEO wouldn't tell us what those ideas were. But considering Desperate Struggle's focus on revenge and Wii Remote swordfighting, one would think monitoring a player's pulse would be regularly up.
Vitality Sensor use in Suda's upcoming game probably won't happen, but Wii MotionPlus support might. Suda says Grasshopper is "going to definitely try to use" the peripheral for No More Heroes: Desperate Struggle, one of the few properties the developer has worked on that's spawned a sequel.
If they can figure out how to dual-wield beam katanas with one-to-one motion tracking, we could have something interesting on our hands. Just not our fingers.
