OPx knows what he's talking about. Developers/Voice talent have a very strict contract, meaning if you were to leak any info out about the game. Rockstar would basically then own your house, car, dog, ect. Legal teams for Publishing companies mean business, they do NOT play games, they are protecting they're investment. Look at what happened earlier this year when Bethesda legal team shot a cease and desist letter to Mojang for using the word Scrolls in their new game. If Gottfried was under contract he would certainly know better then to speak when he's not supposed to. Also R* doesn't like using big time voice actors.
Say what? Most of SA was big time actors.
