Xbox has Oct. but PS will destroy Nov and Dec.I think Halo is being rushed anyway in order to slow down the onslaught once MS was not able to secure a COD bundle and a BF bundle,which I am sure they tried to.They bet on the wrong horses this generation paying for TitanFall and Tomb Raider.Halo has never sold the Xbox alone and destiny,COD and BF all offer the same experience.Most of their top games are just shooting games except Forza with Scalebound being the only none shooter for the future and that won't sell either.
