We were wrong. Despite the studio's lead network engineer, David Aldridge, stating as much on a GDC panel slide; Bungie has come out to quash the rumours, stating it was a "joke".

“In rehearsal Aldridge was convinced that everybody got the joke,” the studio said.

“It was all in the delivery, he assured us, and he was certain it was clear that he was playfully riffing off of the recent rumors. Unfortunately, most people can’t figure David out – they can’t process him. And we don’t expect them to. You can’t process David Aldridge with a normal brain. You’d need tiger blood and Adonis DNA.”

Whoops. (Except we still think Bungie are making some kind of MMO. This is clearly just a cover.)
