Also…is James Earl Jones still the voice of Vader?
I don’t think it’s confirmed but I’d say it’s a safe bet. He voiced Vader in Rebels and Rogue One and while his voice sounds a little different, it’s still undeniably Vader and very intimidating.
If he’s chosen not to take the job, I think Scott Lawrence who has voiced Vader in multiple video game projects since Tie Fighter in 1994, and did a particularly fantastic job in Jedi Fallen Order, would be a great pick.
