I saw the documentery but towrard the end they something about slo mo and stop time and showing off major enents in the fight does that mean at the end of the fight you can review?

one thing iv'e noticed is that bungie not on asingle screen shot or video has shown a player with a sword and I'm a little concered about how the sword is going to look as a secondary weapon like will it be activated while it's on his back or will it be turned off beacause when ever I have the sword on halo 2 I try to hide the fact that I have it and if the sword is turned off while you have it will be a bit harder to see and one last thing will the sword have a limited amount of energy on VS just like it does or will it remain the best defensive weapon for CTF ? Iv'e also seen a couple of coments on the arbiter confirmed in the story but not playable I don't think he will be playable otherwise we would probably see some covenate elites in multieplayer. just a couple of thoughts Iv' had in my head.
