People actually believe this? The way this is written should ring alarm bells, it's the same tone used in those so called 4 chan leaks.
Also another hit on the credibility is that it's not leaked through Japanese media. How could a Western person have access to this info, and supposedly leak it to some random youtuber, rather than contacting something like the well established Kotaku that leakers often use. Makes no sense.
It all sounds like your usual gamer outrage. The gamer culture loves their online dramas.
