Following the sudden and unexpected departure of Overwatch game director Jeff Kaplan from Blizzard, assistant game director Aaron Keller took his place. Shortly after that, he was interviewed by Gamespot and the lengthy chat includes some very interesting tidbits about Overwatch updates that might be released soon.

Yeah, there are really big features and systems coming soon. As big as anything we've built for this game, and the amount of resources that we've poured into these has been massive across almost every aspect of our team to do it. Those will be coming out soon. I don't have a date that I can announce right now. Hopefully, it's something that we'll be able to start talking about sometime in the near future, but I am very excited for them and I can't wait to see people's reactions.
