Breh, it was just a prediction made by a guy who's been notoriously wrong in the past. Sony has went on record saying Destiny boosted their console sales numbers to the biggest since Christmas. He's been trying to hammer that prediction down our throats since the free game promotion Microsoft had last month.
The one month I would actually give Microsoft is November because of MCC. I would say October due to the Sunset Overdrive white bundle, but that game and it's hype wasn't as big as Titanfall, and the quad still won that month so who knows.
