A post on Blizzard News from Aaron Keller has the game director's take on the current state of Overwatch 2. It's a lengthy post covering a lot of ground as the developers have been working to incorporate player feedback into the future of the multiplayer shooter. One of the game's burning topics is seasonal resets, and part of the update discusses the future of those:

Players have provided a lot of feedback on the reworked system that launched with Overwatch 2. One of the biggest issues that players bring up is how their experience has been affected by a partial rating reset at the beginning of each Competitive season. This (along with some matchmaking issues) has caused a lot of confusion in matches. Starting with Season 4 we'll be removing this reset, and players should have a much clearer picture of their rating, season-to-season.

Internally, we’re still discussing whether a rating reset should be a part of the Competitive system. We believe that a reset could make sense in OW2, but it would have to take a different form. We’re currently asking ourselves; what if a partial reset happened at a much greater time interval (perhaps yearly) and coincided with a greater set of changes to the game or to the Ranked system?
