Patch 2.3.0 currently has no release date and will most likely come to the PlayStation 4 and Xbox One sometime after the PC release. Legendary powers are still restricted by class so a barbarian cannot equip a power from a weapon only usable by the monk. The Kanai Cube can be used with: all mainhand and off-hand items, hands, legs, feet, chest, belt, wrists, shoulders, and head armor, as well as rings and amulets. If you reroll an ancient there is also no guarantee it will stay that way, so use at your own discretion. The cube can also reroll legendary items for more favorable stats, or in order to roll an ancient legendary. The cube can break down a legendary item and add its unique power to a collection list, which can then be equipped and swapped out by the player. The cube will be a way for players to gain a legendary items power without having to equip it. In the patch trailer, one of Kevin's coworkers explain that he was very particular about his armor layout, and they used that for the character of King Kanai. This version of the cube was watched over King Kanai, whose ghost appears and bears the same armor set that Kevin used for his barbarian character. The Kanai Cube is named after Kevin, and also serves a follow up to the Haradric Cube first seen in Diablo II.

Blizzard has decided to show their love for a friend and coworker by introducing in Patch 2.3.0 the Kanai Cube and the Barbarian Temple, two features Kevin wanted to see brought into the game. Sadly, he passed away due to a rare cancer called Alveolar Soft Part Sarcoma (ASPS) on October 17, 2014. Kevin Kanai Griffith was a developer who joined Blizzard to help with World of Warcraft's Burning Crusade, Wrath of the Lich King, and Mists of Pandaria expansions, as well as working on Diablo III.
