The Wii Fanboy staff tend to be divided on the matter. Dave is predicting a Wii Fit add-on pack or new Channel update that uses the leaked pedometer peripheral, Wesley suspects this rumor could mean the unveiling of Kid Icarus or Punch-Out!! (though says his "money would be on Kid Icarus"), JC forecasts dates for Disaster: Day of Crisis and Fatal Frame IV, while Mike and Dave both think we could see a solution to our ongoing storage woes (as do I, actually).
Over to you, reader. What has Nintendo got up its sleeve?
