Microsoft's E3 2011 briefing isn't until 9:30 AM Pacific. Someone forgot to tell the Xbox.com guys that, because for a brief moment around 9:30AM Eastern, fans caught a glimpse of Halo 4.
Dance Central 2, Halo 4, Halo: Combat Evolved Anniversary, Kinect Star Wars, and more appeared in name only this morning, the links attached to the name leading to error pages. After a quick refresh the page reverted to its original teasing state, but not before I managed to snap a screenshot.
For more news on these games and more, be sure to stay tuned for Microsoft's proper E3 2011 reveal later this morning.
Thanks, Larry for passing along the link!
