Although Microsoft still did not reveal its official launch date, despite the fact that Sony has already announced that the Playstation 4 will be coming to the US on November 15th, Kotaku managed to find some info placing the launch date for the Xbox One on November 8th, a week ahead of its competitor.
Although nothing is still carved in stone, Kotaku's source who works for a marketing company that handles signage and product placement for Walmart, noted that an internal email for a company conference call puts the launch date on November 8th. This could make sense as that way Microsoft will have a full week of advantage over Sony and its November 15th Playstation 4 launch date.
Of course, nothing is still confirmed and dates could easily change but this is one of the first solid leads on Microsoft's Xbox One launch date.
