Like a few others have said I'm not sure if it will really help the Wii U sale a lot, but it financially it will help Nintendo a ton.
I'm planing on buying way to many of these things
Bets:
1. If the Wii U sells closer to 10 million LTD by 1/3/2015 I win. If it sells closer to 9.5 million LTD by 1/3/2015 OfficerRaichu15 wins (winner gets 2 weeks of avatar control)--Lost.
