The only thing I can say about that is that I hope they intigrate Sprinting into the controls permantly. I mean really, think about it, if your a kick ass spartan like Master Chief, you are going to be able to sprint for periods at a time, like in call of duty. I mean its a great thing to have. You shouldnt have to pick it up to use it, it should already be there to use along with other stuff you have. No you shouldn't have infinite sprint like in some game types people make, but it should wear off after a certain distance you run too. I dunno, thats my opinion and I hope they decide to do that.
