'Gearbox is NOT working on a Halo title for Microsoft'

Hey guys and gals, have you been keeping up with this Gearbox/Halo thing? Yesterday, we heard Gearbox president Randy Pitchford kind of stumble over himself in response to the rumored Halo game. Today, it's a different story, with the Halo Waypoint Twitter account declaring, "For the record, Gearbox is NOT working on a Halo title for Microsoft."

Before you start going crazy with cries of, "But, it's Twitter!" and "It's probably a fake!" realize that we've confirmed with Microsoft's Major Nelson that it is, in fact, a legitimate account. Is that the end of that, then?
