Well there you have it, all the rumors were true. Blizzard is going to release a special Loot Goblin amiibo sometime this December. When more details are shared, we'll be sure to bring them to you!
UPDATE - This amiibo will be a GameStop-exclusive in the states. Also, it appears that this amiibo is just a slight redesign of a Treasure Goblin figurine that Blizzard released awhile back. You can check out that original figurine below.
