Maybe, Overwatch 2 will replace the original game on release, which will become completely unplayable after the release of the sequel. This became known from the session of questions and answers on Reddit.
Game Director Aaron Keller was asked about what the term “Early Access” means in relation to the title, and about the replacement of the PvP mode in the original, or about the end of support for the game:
We use the term “Early Access” to indicate that this is only the beginning of the development of the game. We will release a shooter with new heroes, maps and features, but with each season there will be even more – every 9 weeks.
When Overwatch 2 launches on October 4, it will replace the current service game.
This is an unofficial statement from Blizzard and should be treated with caution. The main problem is that in the sequel the matches are 5v5, and in the original 6v6. Players who do not like 5v5 may not like this development option.
Overwatch 2 will be released on October 4 on PC, PlatStation and Xbox consoles. The game will be free-to-play, and a paid PvE campaign will be released next year.
