This has been a good year for Overwatch but Blizzard has no plans to slow down anytime soon. The developer has already started teasing about some of the updates that Overwatch will be getting next year.
According to the Director of the game, there will be a new DLC map next year called Oasis. The new DLC will be released early 2017. They also added that players can expect to see more events from them.
The game is currently celebrating the holidays with the new Holiday event but come New Year and they will be seeing a New Year event. Of course, we are going to see more characters being added to the game. We do not know who the new characters are but we can be sure that Blizard will start dropping hints in the game just like what they did with Sombra.
All in all, it looks like 2017 is going to be an exciting year for the fans of Overwatch.
