According to Mike Morhaime: “Titan is an exception to that where we wanted it to be our next generation, our sequel to sort of World of Warcraft. We took a lot of our senior developers and put them on this project. And I think where we really failed was we failed to control scope. It was very ambitious.”

If you remember there was so much hype few years back of Blizzard working on next-gen MMO or WoW 2.0 as some people were calling it. According to Mike Morhaime the project was cancelled and eventually became Overwatch in 2016.
What does this mean for us gamers waiting for the next big MMO from Blizzard? We know for a fact that developing large scale AAA titles like MMOs takes years so if they are indeed working on the next MMO right now the game won't be out any time soon which is a huge let down. Can Blizzard keep remaining playerbase with WoW until then remains a big question mark.
