By first week, I mean the vgchartz week ending 25th febuary. I'll add that to the OP. Oh, and if you say 100k-200k, i will put your prediction as 150k
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
