OP updated! 357k this week, giving it a WW total of 7.39m after 8 weeks on sale.
It'll get past 7.5m next week...so I'll probably end up being about 280k off with my total prediction. The 1st week crippled me, but it's been holding fantastically well since then!
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
