iGR: "A verified industry insider has just outed the development of Crackdown 3, but he/she wasn't done there. They've also given the exact date of when Microsoft will be releasing the Halo 2 Anniversary Edition on the Xbox One."
Further evidence may be at hand. Halo 2 originally released on November 8th, 2004. The insider reported that the Halo 2 Xbox One release would happen on November 11th, 2014. The closest date Microsoft could possibly have for a 10th anniversary release of Halo 2. Food for thought.
