New voice? Sounded like Dominic Armato (who was already confirmed reprising the Guybrush role) to me.
I might be wrong. Been awhile since I played a Monkey Island. I was assuming Guybrush's original voice actor was older and was probably too gruff sounding now, but he's actually only like 6 or 7 seven years older than me.
The Monkey Mechanic guy's voice sounds a lot like him, you got to give me that.
