I'm not sure why a load of people are flinging their arms up in the air and trying to defend PS4. We all know that the PS4 will overtake Wii U in Japan, we don't need anyone to tell us that. The question posed was when. Of course the Wii U had extra time to build its lead, but that didn't exactly help it in any other market in the world - I mean it trails to PS4 AND Xbone pretty much everywhere else.
