Yesterday, Eddie Makuch from Gamespot reported that Overwatch will be shipping on multiple platforms, and that the game is slated to be released in, or around, June 21, 2016. They linked the official Overwatch website, and an additional image as sources. Unfortunately the Overwatch website currently does not indicate anything about a multi-platform release, and the image link has since died. Additionally the game is anticipated to retail for 60 USD.

We are excited to share more information about Overwatch with everyone at BlizzCon this weekend--so be sure to tune in to the opening ceremonies.
Blizzard Representative.

Blizzard is expected to release more information with respect to these matters today, and tomorrow, at BlizzCon 2016.
