i dont think glitches would be a good idea to keep cuz u want to keep that halo felling just like it waz 10 yrs ago so my answer would be to take out glitches :|
i dont think thry should cuz it would take for ever they r already making halo anniversery and halo 4 and also dont u wanna know wut happens after halo 4 maybe a halo 5 and if they make a halo 2 itz goin to take another 2 yrs
we would it be reach we took it back from the covenent along time ago and reach is not a huge structure that open a huge mouth it could just be a new halo or some new type of halo
i think itz another halo but it can be also a brand new type of halo we will have to wait until du game comes out or until 343 industries tells more about the huge sturcture
