Or could be that whatever VA theyre getting for these characters are going to be long term commitments and Jet's actor is 75 years old. I think that had a lot to do with it.I really don't want to say something that isn't accurate (as I'm essentially pulling this out of my ass), but I'd assume it might have been something like S-E wanting non-union voice actors.
That already happened with RE2 Remake this year iirc.
