Blizzard has thrown a lot of money at the inaugural season of the Overwatch League. Since it’s announcement last year, they’ve built a brand new stadium, they’ve wrangled a handful of the biggest owners in traditional sports and they’ve been advertising like crazy. 

The two things they haven’t had are a full roster of teams and a start date. Fortunately, both were finally announced today as the final three teams solidified their spots. 

A Philadelphia based team, owned partially by Comcast, as well as Team EnVyUs and OpTic Gaming, representing the cities of Dallas and Houston, are the final three teams to join the Overwatch League. This brings the grand total of teams to twelve, making it one of the larger single esports leagues around.

Although teams will be representing cities from all over the world, including Shanghai and Seoul, all games will be played in Burbank, California at Blizzard’s brand new venue, Blizzard Arena Los Angeles. The preseason will kickoff December 6 with a few exhibition games. Then the regular season will get underway on January 10. It’ll run through the month of June with the season finales slated for July 2018. 

There’s still a ton of information we don’t know about the upcoming Overwatch League. The definitive schedule is still a mystery, as is the format. It’s unclear how many games will be played each week and how scoring will take place. We also don’t know the names of the teams. With a mixture of esports and traditional owners, it’ll be interesting to see how naming works. Will OpTic Gaming become the Houston Optics? Are the Immortals going to become the Los Angeles Immortals of Anaheim?

Blizzard has bet big on the Overwatch League and a lot of people are expecting it to fail. At the same time, Blizzard has managed to convince some of the biggest names in sports to participate, including the owners of the New England Patriots, the New York Mets, The Philadelphia 76ers and more. Not to mention all the established esports organizations who’ve jumped on board. Like it or not, this could be the first best shot for esports to break into the mainstream sports scene. Only time will tell.
