Not really. They needed to mo-cap new PP scenes for MM. People underestimate what goes into mo-cap. There's a lot of manual work that goes into it once the motion is captured, to ensure that the in-game model's movements sync up properly with the capture, otherwise the results are janky. If you're capturing new scenes, and you discovered during the dev process of the original game that a lot more work was needed than necessary, due to the differences between the game model and the actor, you will change the PP model for MM. What would fan reactions be if they only changed the PP model for MM, but left the old one for the original game? How disjointed of a transition from remaster to MM would that be?
So, the logical thing then would be to change the model in the remaster, and you'd end up having fewer manual edits to make to the capture that's already in the database. This allows better continuity for gamers going from Remaster to MM to Spidey2. It's easy to blow real work off as excuses when you have no idea of what went into the production of the game. But understanding how mo-cap works, and how much has to be done after the actors are captured, you can better understand how this provides efficiencies in development workflow. Efficiencies that pay off for as long as they keep the same PP actor. It also allows them to create a Remaster that is consistent with this more efficient workflow, because you're not changing the in-game model between games. The only change here is going from the original release to the Remaster, but in that regard, it's not different than rebooting a film franchise with a new actor. No one cared that we went from Tobi Maguire to Andrew Garfield to Tom Holland. The Holland movies are beloved because he's been the best fit for the role, and we could care less that he looks different from the other people who played the character. I don't understand why this should matter for the games at all.
