This is according to a PepsiCo terms and conditions document dug up by NeoGAF which is tied with a Microsoft promotion that gives away "an Xbox One every two minutes" November 5 - January 17.
"Xbox One has targeted launch date of late November 2013," reads the text. "Therefore, the initial shipments may be slightly delayed; please allow 12-14 weeks for delivery."
Microsoft has yet to provide an official release date for the console beyond a "November" release.
Meanwhile, Sony's PlayStation 4 releases in North America on November 15 and in Europe on November 29.
