Awesome thread Superchunk! Looks like the Wii U is off to a fantastic start. I personally think the first year is going to be better than the Wii but after that it will start to lag behind until about 3-4 years later where it will start selling more than the Wii did in 2011 and 2012 respectively.
BTW you should add a graph or two because graphs are awesome. Heck and while you're at it a pie chart as well because pie is delicious.
