A few days ago, the Sun newspaper in the UK said the release date for the PS4 was November 21st, 2013. An advertisement in the Netherlands has a different release date.
Media Markt store in Amsterdam, Netherlands has put up an advertisement saying the PS4 release date is November 13th, 2013. Apparently, other European retailers have pegged November 13th as the release date too.
Sony itself has refused to comment and still says that the release date for the console is “Holiday 2013”. It’s possible they are waiting until Microsoft announces a release date for the Xbox One first since both consoles are supposed to come out in November.
