We recently reported that the LA Valiant will host their matches in the Microsoft Theater from Season 3 onwards. This might point to a potential timeline in the Overwatch League as we will most definitely be seeing the Second season also being on LAN in Burbank, California. The first season is being held at the Blizzard Esports Arena in California and all the twelve teams are playing on LAN at the venue.
With the LA Valiant moving to the Microsoft Theater in Season 3, looks like the first two seasons of Overwatch League will be held at the Blizzard Arena in Burbank.
