Concerned that motion controls aren't quite precise enough to get the job done? No worries -- Nintendo's on it. While we expect more details at tomorrow's E3 press briefing, a press release has surfaced for the Wii MotionPlus, an add-on for the Wii remote that "allows for more comprehensive tracking of a player's arm position and orientation." That opens up nearly as many questions as it answers, so we'll be watching tomorrow's conference even more excitedly. If things get more any more intense around here, well, we just might explode.
