Educated guess for Season 4 premiere?

Season 1 - Release date July 26, 2019.
Season 2 - Release date September 4, 2020.
Season 3 - Release date June 3, 2022.

I am assuming Season 2 was slightly delayed (post-production only maybe or very-very little of filming due to COVID)?

I am also assuming Season 3 was perhaps more impacted due to COVID than Season 2.

I doubt we will get Season 4 by June 2023, but I assume it will be before September.

So maybe mid-late summer, between July 2023 - August 2023?

I believe I read a couple of weeks ago Karl Urban saying they planned to begin shooting by mid August 2022 until December 2022.

Any thoughts? Have you heard anything else? Educated guess?
