There are many new datamined wraps, materials and armor packs. It seems some of them, including the new crystal armor, will be available via the Cataclysm event and not in the store. 👍
So it appears we'll be receiving melee weapons in the future, plus new armors and skins! Thanks to Anthem Archive, we get an indication of what's possibly coming up in Anthem's near future. Featuring gameplay of the new Sunken Stronghold with the Ranger. Source: Open World Games
