A few days ago I have posted that one of my sources told me that a new Xbox console will launch in 2017. Shortly after that several big news sites reported the same. This is the reason why I give this source so much credibility that I post the next thing the source told me. According to that source Mario Party 11 is in development for Wii U and will launch later this year. It will be the last First Party Wii U exclusive game.
As I said after the Xbox thing ended being true I also believe this.
