Xbox One is now at 745k vs 678k for the PS4+Wii U with one week left. If VGC is anything to go by then this is gonna be close
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
