As always, this is Grubb only making some personal guesses trying to pass them as insider info.
Insomniac already publicly said that the game will have a mature tone and will be dark and very violent. Also said that won't be an open world game but instead a more linear game, more or less like their God of War.
Insomniac also traditionally has one or more release per year. In 2022 they released the two PC ports, in 2023 will release Spider-Man 2 (made by the Spider-Man 1 team) so Wolverine (made by the Morales team) will release in 2024. And obviously will try to don't release Spider-Man 2 and Wolverine too close, so if Spider-Man 2 will be released in Fall 2023 they won't release Wolverine early 2024, but instead they'll release it in the 2nd half of 2024.
Insomniac is maybe the most reliable AAA studio, I highly doubt they may ever considered a 2025 release for Wolverine.
