[Update #2]: Overwatch 2's PvP mode will finally be heading into Closed Beta this April 2022.
[Update]: Blizzard have now shown and detailed the comprehensive Sombra and Bastion reworks, as well as offered a brief peek at the new Push game mode.
Despite Blizzard saying we'll get more Overwatch 2 information throughout this year, we have sadly received very little in terms of new details. In fact, outside of the PvP focused livestream back in July that showed off a bunch of maps and confirmed that the PvP mode will be 5v5, we have learned practically nothing about how Overwatch 2 will actually play.
There is a glimmer of hope on the horizon, however, as Blizzard has just announced a brand new Overwatch 2 update! While the specifics have not been revealed just yet, you can expect to learn more about the various Sombra and Bastion changes this September 25th during the Overwatch League finals.
If you're willing to indulge a bit of my speculation, I'd say that we'll likely see full reworks of both heroes. Bastion has been a terror to new players and nearly useless to veteran players since he was added to the game, while Sombra is one of the most annoying heroes in the entire game to play against since her whole shtick is making you unable to do anything. As such, they are both clear candidates for reworks that would emphasize their individual strengths while toning down some of the annoyances.
Whatever the future may bring, I'll make sure to let you know once the big reveal goes live. Until then, you can read a little bit more (with the emphasis being on little) about Overwatch 2 by hopping over to the official website.
And just for good measure, I'll leave you with the brief recap of the aforementioned PvP livestream. Enjoy!
