There should be dual wielding in halo 4. I've been playing Halo 3 since 2007 until today. Its still great, people still play it everyday and yet some people like myself traded in reach. It was too different in some ways, halo 3 has always been amazing with multiplayer. If Halo 4 doesn't have dual wielding im going to be angry but ill just live with it because no matter what Halo 4 does look amazing.
