That source you used stated PS4 was at 7 million in July...Unless that 100 Million Sales is of March 2014 (Which I believe it wasn't). That is factually incorrect.
Infact that source you used, didn't even use its own source material correctly. IGN even wrote it should be north of 8 million. (Infact it might have been closer 9 Million at that stage) since it was 13.5 in September.
That is how we get misinformation...when places don't even use their own sources in corrective methods.
The original information itself is strange video.
