halo wars 2 themed update

343 should have a halo wars 2 themed mini update in halo 5 to build hype for the game and possibly even tease how the story could go. My idea is that the update includes an arena map that takes place on the spirit of fire but takes place right before or during the beginning of halo wars 2 and clues to what happens to the spirit of fire and its crew are hidden throughout the map subtly and if they do it right the map itself could be a trailer for the game in a way. Along with this they could add mark iv scarred since red team looked like they were in a serious fight in the first hw2 trailer shown a while ago, some emblems like a spirit of fire emblem and maybe a banished emblem. Small stuff like that and maybe even an energy mace that could be a new req and a weapon on the arena map. What do you guys think, should they add a halo wars 2 themed update later on or something like it?

Yeah, small things like that would be cool.
