I know what's happened...
ioi DELIBERATELY undertracked the PSV & PS3 to teach Sony a lesson about releasing their figures. It all makes sense now! Well played, ioi.
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
