mario party 7 came out in north america on november 7,2005.Australia june 8,2006.japan november 10 2005 and europe feb.10,2006. As you all know,mario party 8 came out on MAY 29TH 2007! do you see my point? from 2005 to 2007,MP7 to MP8'S release,well thats TWO YEARS!so they have not released a mp game every year in north america and japan. so,there will be a mp9,but why does a two year gap mean mp9?because,if theres a two year differece between mp7 and mp8,then there will be a two year gap between 8 and 9. so that means 9 will come out in 2009. you get what im saying?nintendo lied to north americans and japanese people. it took two years for us. so everyone,since its been a year since mp8,dont panic that the series ended because it didnt end in the two years between 7 and 8.9 will come out in '09! sources:
