We’ve got the strongest games lineup in Xbox history right now, with 2015 blockbuster exclusives like Halo 5: Guardians, Rise of the Tomb Raider, Fable Legends, and Forza Motorsport 6, and more we’ll announce in the coming months. With so many games launching this year, moving Quantum Break to 2016 extends our incredible portfolio into next year with a monster new IP.
