Imo, the only misses of the leaks are:
No steve Blum- I get that Insomniac likes to create a unique voice but damn.. I have seen videos with the voice actor and he doesn't sound that bad.. Pretty hit/miss
Love interest- he's in japan, fighting the hand. I don't get why they used jean grey when mariko is right there, but its whatever at this point.
release date- 2026
also, the footage of the game is pre alpha, im 10000% sure they would add more gore, dismemberment etc.
