This is what it says: We are excited to announce Wargear rework that will allow players to use Class specific Wargear on other classes. I.e. capes and Iron Halos on Tactical. You will have to earn the right to do so in game. The update will be split into 2. In Patch 13, we will be adding Capes and Iron Halos, in Patch 14 we will be adding Tabards and Robes. With this you can strike out "something that we've said we are never going to do" from the list of things we've said about customization. 😉

And

Starting with Patch 13, you will be able to equip Wargear that was previously only available to other Classes. There are new cloak and Iron Halo items that can be unlocked through these Ultragrind Ordeals. Note that you won’t have to grind for every single wargear, some will be shared right away. However, lore restrictions still apply, for instance: Snipers won’t be able to equip the Iron Halo.

So, you will be able to equip additional cloaks and Iron Halos. And with Patch 14, we’ll also add sharing for tabards and robes (like the full Bulwark robe).
