If you've been playing some of the biggest video games of the past few years. The odds are very good that you've heard the voice of Nolan North. He's been the voice of Desmond in Assassin's Creed, Nathan Drake in Uncharted, and the Prince in the Prince of Persia reboot. If you threw a rock into the Giant Bomb database, you'd have a 70% chance of hitting a game he's voiced in. When it comes to comics, he's voiced characters from Deadpool to Hal Jordan when animated. I could go into his movie/TV credits, but you get the point. He's a popular guy.
When I got curious if he's ever voiced a character for anime. I saw his credits were slim. Only one listing, but it's a big one. He isn't taking his first steps into anime as some random filler character or short term villain. He's taking on the part of the grand puppet master of the entire Naruto series, Madara Uchiha. While he's already voiced Madara in the game Naruto Ultimate Ninja Storm 2 that was released late last year, but that was never a guaranty he'd take the role on for the English dub of the anime.
I don't believe that Madara really drops the Tobi persona until he hears of Itachi's death, and the air date of those episodes have yet to be announced. You can get sample of what that could sound like in this clip from Naruto Ultimate Ninja Storm 2:
