Oooh only just realised this was bumped..
It's currently on 1,741,857 with 8(?) tracking weeks left in the year so it needs to sell over 657k weekly until the end of the year to prove me wrong.
WHO'S CRAZI NOW GUIS?!!
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
