Since then, the ESA (which represents the video games industry in the US) has released a
full statement on the matter, confirming that Nintendo, Microsoft, and Sony "will require paid loot boxes in games developed for their platforms to disclose information on the relative rarity or probability of obtaining randomised virtual items."
Additionally, the new measures, which are expected to be implemented next year, will apply to all games that add loot boxes in a post-launch update.
According to the ESA, a number of publishers - specifically, Activision Blizzard, Bandai Namco, Bethesda, Bungie, Electronic Arts, Microsoft, Nintendo, Sony, Take-Two, Ubisoft, Warner Bros, and Wizards of the Coast - have all agreed to disclose the "relative rarity or probability of obtaining in-game virtual items from purchased loot boxes" in their own titles, and "in a manner that is understandable and easily accessed". This will occur "no later than the end of 2020".
