As indicated in the original story there were reports that a Blue Xbox 360 is going to hit the markets in October, this has not been confirmed.
Three bundles were announced and will be exclusive to Walmart in the United States.
The other two bundles announced are:
500GB Holiday Value Bundle and a 4GB Kinect Bundle.
The Holiday Bundle will be available to retailers next week, however the Kinect Bundle will be exclusive to Target. The bundle will include the consoles, camera, Kinect Adventures, Kinect Sports and Forza Horizon all for $250. The release date of the Kinect Bundle has not been provided as of yet.
This is a leaked ad so until it is published we will have to take this as being a rumor however, according to this Walmart ad a Special Edition Blue Xbox 360 Bundle is being released in October.
The bundle will include Call of Duty: Black Ops 2 and Call of Duty: Ghosts.
If this source is accurate you will be able to purchase this bundle (US only for the moment) for $249.99 on October 7th 2014.
