The upcoming Closed PvP Beta for
Overwatch 2 has been given a start date April 26, and even though invites will be limited to those that own the original game on Battle.net (PC) your "Battle.net region" will factor in to who will be selected. Alongside hardware specs, though on that front what has been announced looks to be fairly modest.
This probably means players in Australia won't be included in the first round of testing (a full Open Beta is also on the cards for 2022), though Blizzard is noting that "select journalists and community contributors from around the world" will also be included. So... maybe.
Also console players will be able to jump in on future tests. All of these updates arrived as part of a new Overwatch 2 PvP Beta FAQ
that's live now.
