3DS hardware seems kind of low in America. There are two weeks of greater hardware sales for the handheld this year -- already kind of suspect. The first was the week ending March 30, coinciding with the release of Luigi's Mansion: Dark Moon. It opened with 271k sales and the 3DS sold over 70k. The second was the week ending June 15, when Animal Crossing: New Leaf was released with an opening week of 249k sales. The 3DS sold over 83k that week.
These two games opened with under 300k sales, yet pushed more hardware than a new Pokemon generation debuting with over 1.3 million sales -- plus a new model, the 2DS.
I don't like playing the "undertracked" card, but it's a possibility here. The numbers are suspicious to me.
Bonus Round: Did you know that this is the third-highest week for 3DS software in the US since its release? The only weeks higher were the ones ending December 10 and December 24 of 2011. Pokemon X and Y alone sold more than the entire 3DS software library in any single week of 2012, including the Holiday season.
Oh yeah congrats PS3. :P
