Okay I saw this kind of late.
ITS TIME TO MATH GUYS!
So, knowing that Uncharted sold 26.5K and topped Overwatch on Xbox One, we can calculate the upper limit of total Overwatch sales.
So assuming that Overwatch XBO and Uncharted 4 were neck and neck:
Overwatch would be:
>26,500k XBO at 36% share = ~73,600 Total (All Platforms)
and ~36,600 (47% share) for PS4 and
~13,250 on PC (18% share)
Obviously the real numbers are lower but this calc approaches the max sales possible for Overwatch.
