Overwatch has been in a sort of a hot seat, during the hubbub about the controversy surrounding the Blizzard protests. Long story short, a Hearthstone player was banned for his views on the Hong Kong protests. There are a few stories that are related to this, and one of them was the cancellation of the launch party for the Nintendo Switch version of Overwatch in New York. (Overwatch was released for Nintendo Switch on October 15, 2019.) At Blizzcon 2019, not only did Blizzard reveal Diablo 4, they also revealed Overwatch 2.
Blizzard describes Overwatch 2 as a “shared” experience, where you can move your character from the original Overwatch, to the new Overwatch 2. What it sounds like, is Overwatch 2 is an updated version of Overwatch, with upgrades, which is possibly the reason why they’re making it easy to transfer your character. So, whatever you’ve done in Overwatch, may possibly be available on Overwatch 2, so you don’t have to re-do your character grind (leveling up). Not much else was revealed about Overwatch 2 at this time.
