Blizzard is rolling out a beta test for the Overwatch World Cup Viewer, a bit of tech that will let viewers watch the upcoming Overwatch World Cup via the Battle.net client, giving them access to all of the camera tools previously reserved for Overwatch League's professional esports observers. This means viewers will be able to control the camera, switch between first-person and third-person, and choose which player's view they want to watch. 

This is great. I said several months ago that I was disappointed by the Overwatch League All Access Pass's Command Center, which added alternate in-game camera angles and real-time stats, but didn't let the viewer fully control the camera. Overwatch League's broadcast crew does a great job of following the fast-paced action of OWL matches, but sometimes I just want to follow a specific player the entire match, or watch only from the tanks' perspective. With the new OWWC Viewer, I'll finally be able to do just that.
