Looks like we will have to wait until at least 2023 to play Diablo 4 and Overwatch 2.
Since its announcement, Blizzard has shared development updates on Diablo 4 but has said and shown little when it comes to Overwatch 2.
“We have new leadership on both Overwatch 2 and Diablo 4, and both are seasoned Blizzard developers with over 30 years experience at the company between them,” said Ybarra.
Diablo 4 was announced in November 2019 at BlizzCon, as was Overwatch 2.
