Only a small surprise, it looks like someone has found the code for authentication checks for Xbox One and PS4 while datamining Overwatch.
There has yet to be an official announcement about when Overwatch will be available for consoles, though with Blizzcon happening next week, it seems likely that we'll know for sure sooner rather than later.
As previously reported, there have been hints for a few weeks that Overwatch would be coming to consoles soon without any concrete evidence of which consoles would get the game. The closed beta only began this week, so it's too early to tell with any accuracy.
In other recent Overwatch news, Blizzard's customer support Twitter recently warned players to be wary of fraudulent emails containing beta keys.
