Mafia III's IMDB page is pretty sparse, no sooner do credits go up and they get taken back down. Even actors like Rick Pasqualone who voices Vito, who we know is in the new game, is no longer listed there. I guess they want to keep everything hush hush.
However today I saw an interesting listing there, Ethan Korver will be voicing "Franco Tomasino". Is it possible Henry had a son before he died? Could be a nephew I suppose, Henry had 6 brothers that we know of.
There's also another listing for Matt Kaminsky, who will be playing "Handsome Harry Robicheaux" and "Marcona Informant".
I'll keep an eye on the IMDB page and post any more updates I see there and I'll be taking screen shots as well.
