Besides new sound files, a new entry of 'golden loot' was also found. There are also findings of references to 'golden loot boxes' and 'golden loot' in the strings dump of Overwatch. Here is a texture for the new golden loot box.
The Overwatch community has been making all sorts of guesses on what will the next event be and what does the golden loot box mean. Summer is just a month away which could eventually mean the return of Summer Games event. As for the golden loot box, majority of the people are specualting that Overwatch will soon implement Heroes of the Storm loot chest system where there will a rarity for these loot boxes, which makes it easier for player to obtain a least an epic tier item.
It is still too soon to tell what is going to happen next in Overwatch. For the time being, just enjoy the Anniversary event while it is still available and try to unlcok all the awesome event items.
