The Fallen is going to be a pretender. "Give me your skin!"
OptimusMagnus3
Personally, this guy looks like he would make a good evil scientist. I smell a Dr. Arkeville reference in Transformers 3!
Autobot_Wall-E
Maybe he'll be an evil doctor who resurrects the Fallen? I hope not.

I really like that idea! Tony Todd would be perfect for the role.

Sam died in ROTF and briefly went to Transformer heaven. Would it be too farfetched to speculate that when the Fallen died, he was reincarnated as a human?
Vince
I bet they'll have the fallen take on a human form or something….
Moy
Oh shit, is the Fallen making one las appearance..?
eagc7
well that removes a possible return for the fallen
never mind lol, then i guss fallen woudl return but i doubt it,
Rob Almighty
Tony Todd is the man.
Keroshino
well when i talked with him it sounded like that could still be happining..
he just also hinted that he "might" also be appearing on-screen
i told him that would be pretty cool
Guardian_Prime
Todd should be Dr. Archeville. He fits the character I think.
SPLIT LIP
Tony Todd back is great. I wish he was still doing a TF voice, but his voice is pretty distinctive. But he is cool regardless.
starscream 2005

Ya im pretty sure Orson only did Unicron.
I remember seeing a vid on youtube with a bunch of guys from the transformers movies and that and one of the art directors said orson shot his lines ether a couple days or a week before he passed away so Transformers: The Movie was his last true Movie.
Kinda wish Todd was doing another TF voice maybe he will do both .
Fit For natalie
Tony Todd was great as old Jake Sisko in Deep Space Nine.

I'm fairly sure this isn't the first time Nimoy has announced his retirement.
IIRC, Nimoy said that *HE*(Nimoy) did Galvatron only. Can't remember if anyone actually spefically said that nobody did Unicron but Welles.
MonkeyBusiness
Am I the only one that wants someone in the next movie to say "Hey, you sound familiar?"
KanedaX
Love this guy's voice.
"I'm not a soldier, Major. The day we took hostages, we became mercenaries. And mercenaries get paid. I want my f#%ing money!"
Oracle_Aesir
pretty sure that was just a rumor, the director or someone confirmed that it was Orson Welles who did Unicron completely (no one extra)
Keroshino
the convention was awesome!!! most fun i had in a long time
– I got to meet Leonard Nemoy and got him to sign my Transformers DVD
(it cost me $60 for his signature…but it was worth it)
he even signed it exactly below the picture of Galvatron.
– met with both Garry Chalk and Scott McNeil and got them to sign a "Reboot" artbook
) 
(they are the voices of Hack and Slash
also kept giving Scott Pocky
– met Tony Todd on sunday and got him to sign my ROTF Blu-Ray
(i even asked him if its true that he was gonna be in TF3…and he said "he is" but "gave me a hint that he might be playing a human character")
-picked myself up a Masterpeice Starscream "US Release" ($120)
– Movie Lockdown and Deluxe Ratchet (for $15 each)
and Beast Machines "Mega class Cheetor" (for only $10)
so…yeah…i had alot of fun
