Tagged. Looking like a $250m opening weekend in the US,..with the December multiple Avatar is definitely in its sights. At this point I'd say $2bn worldwide is a given also
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
