Nope, not only do they not fit in the time-line but adding want after want of the gamer would take forever. First we want brutes, we want a change in the elites so they can get head shots easier, then we want new guns, we want new vehicles, we want changes to weapons, then we want some Spartan III's. Finally the game comes out and we want to change some more stuff, it's like taking care of little children who say I want a cracker but really wanted the cookie but they changed their mind half way through eating the cracker.
