FFXV might be overtracked. Just announced that it's at 7.7m sales.
VGC has it at
PS4 Physical : 5.24m
XBO Physical : 1.08m
And apparently leaked steam figures from last month mean:
PC : 0.49m
This leaves only 0.89m for PS4+XBO digital, which would be a digital ratio of just 12.3% which seems too low.
