Just to make the accurate estimate.
[Week 45] CALL OF DUTY: GHOSTS (ACTIVISION BLIZZARD) - 775,000 / NEW
This is the revised number.
Destiny 417,100 (revised after MVC article)
The others two maybe are understimated.
WNO 82k
TF 125k
Because AW > 775k.
Destiny + WNO + TF = 624k
+14% = 711k
I'm sure the Titanfall and WNO are a bit undertracked.
