The announcement of the new Wii MotionPlus add-on has sparked plenty of discussion, and while topics such as supported games, availability, and price have been knocked around, nobody seems to ask the most important question: what will the Wii MotionPlus do to the Wii remote's battery life? 1:1 gameplay isn't so impressive if the gizmo drains a pair of AA batteries right in the middle of a Wii Sports Resort round of doggie discus.
While playing the Resort demo at E3 last week, I asked a Nintendo representative about battery life when the MotionPlus is in use and was actually given a solid, useful answer. When combined with the MotionPlus add-on, the Wii Remote's batteries are good for eight hours of play. Start investing in a small collection of batteries. You just may need them come Springtime.
