I can't believe some people are mocking about the "PS3 is undertracked!!!!1111" stuff.
It was undertracked by 6,884 units! Come on. That is 1721 units per week. Or 3%... this is sooo tiny and people still smell a conspiracy.
Xbox 360 overtracked by 7%. That is in the margin of error as well.
The tracking team did an awesome job for the hardware.
Imagine not having GamePass on your console...
