LeoJ, you have to remember that 500k of the album 'Born this way's sales were bought for $0.99 due to that amazon deal she had during its first week of release, so born this ways USA's sales are quite deceptive.
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
