343 Industries has confirmed that we won’t see the same old armor, and it will undergo some changes. Cortana also will be changing, because at the end of Halo 3 she was coming to an end in her lifespan, and she has been exposed to far to much information than a normal AI usually does, she will develop “muscle.” O’Connor also said that Halo 4 will become a great start to another Halo trilogy.
My Opinion: I think this change will help the new trilogy out, and I am looking forward to it.
Thanks IGN for the information, check them out, and check me out on youtube. http://www.youtube.com/user/THShmoob26?feature=mhee
