No way is Halo 5 getting delayed. Microsoft showed with MCC that they would rather stick to the schedule and ship a broken game rather than delay it to fix it properly. XBox only sells during the holidays in the US, and to not have Halo would spell disaster for them.
I fully expect Halo to make the scheduled release, and then to receive constant fixes to finally bring it to a playabke state sometime in the mid-2016.
