Yeah, considering NPD data and reports from Europe, it is probably overtracked by around 250k.
It should sell a million more by the end of they year, so aroud 8.8 million by January 1, 2015.
Sales will probably be significantly down YoY for H1 without a system seller like Mario Kart. 25k/week is realistic. That is 650k in first half of the year and 9.45 million in totals by end of June.
It will probably reach 10 million around November 2015.
