Also, this is interesting...

To give you some context for this change, I'd like to talk about the past and the origins of Team 4. The Overwatch team was founded in the wake of a cancelled game at Blizzard called Project Titan. That game had many facets, but at its heart, it was an FPS MMO. The Overwatch team, especially at its inception, considered itself an MMO development team. As we transitioned away from that original concept and started creating Overwatch, we included plans to one day return to that scope. We had a crawl, walk, run plan. Overwatch was the crawl, a dedicated version of PvE was the walk, and an MMO was the run. It was built into the DNA of the team early on, and some of us considered that final game a true realization of the original vision of Project Titan.
When we launched Overwatch in 2016, we quickly started talking about what that next iteration could be. Looking back at that moment, it's now obvious that we werent as focused as we should have been on a game that was a runaway hit. Instead, we stayed focused on a plan that was years old. Work began on the PvE portion of the game and we steadily continued shifting more and more of the team to work on those features.

So Overwatch 1 was basically the beta for the planned MMO-style game they wanted to do instead?? Almost everyone knows about the history of Project Titan, but it's news I think that they never stopped holding a torch for that concept. That said, the leaks and rumors of "Overwatch 2" have been there for ages, long, long before it was ever announced... Yeesh.
