First, remember this is a game still in development. Nothing that we have seen in the last two years is absolutely guaranteed to ship with the live game when Overwatch 2 comes out. That is the nature of game development. I try to keep all confirmed facts organized in my Overwatch 2 Quick Facts post, but even a lot of this information is still just information presented and not promises to the final product.
Don’t be frustrated, just keep up with the news as it comes out.
