About the robe in the trailer..

You know that robe master chief was wearing?

Wouldn’t it be cool for it to be something that is special in multiplayer.
Like the halo 3 katana,maybe 343 will give it to people who preorders or buys some super expensive edition and all.Imagine seeing that robe fly in the wind’s direction on a map with windy conditions,or incinerating away from the forerunner weapons.
