Microsoft's next-gen console is listed alongside other major releases such as Madden, Grand Theft Auto V and the PlayStation 4 console, which will be released on November 15th. However, unlike these other titles and midnight openings, the Xbox One midnight opening is not listed as confirmed.
This is only a rumour, and the fact that it's not confirmed suggests that it could be subject to change or be Walmart's best guess at when the console is going to be released. Of course, it was only a matter of weeks ago that it was suspected that the console would launch on November 5th. Either way, we will keep you posted as soon as we hear something concrete.
