Maybe 2012, or 2013, I don't know the universe works in mystery ways.
Literally every year has been the end of the Wii. 2007, 2008, 2009, 2010. Now it will be dead in 2011 and I'm sure it will die in 2012 as well.
I guess we figured out why the Wii has been such a contagious phenomenon, it's because the Wii is a friggin' zombie.
