If images on the r/Overwatch subreddit are to be believed Blizzard will be updating Overwatch in a similar fashion to the Rio Olympic update that occurred during the summer. The image below shows a listing on the Xbox Store that depicts the Halloween update.
The Halloween update would make sense, however Blizzard have not revealed any plans for such an update. In the Olympics update these themed boxes took the place for the original loot boxes featured in Overwatch, and so I expect that if this is indeed true then the boxes will be replaced again. Also similar to the Olympic update, boxes would be available for a limited time and would contain loot such as skins, sprays and emotes.
Do you believe the Halloween update is real? I certainly hope it is, the Olympic update looked like fun. Let us know your thoughts in the comments.
