I'm just replying one more time because of your argument about Wikipedia and university papers. Your argument would apply if this WAS a research or paper for university, but it is not. You can't always rely on it when it comes to science, medicin or something like that, where it took people hundreds of years to gain that information and generally very complex subjects. However, I think we can use it for things like console sales where the Wiki-article itself most likely refers to almost every reliable source.
