No one has posted this here yet, but it was on both the Allspark & Seibertron:
From the AllSpark:
TF Animated cast list
Bumblebee -
Bumper Robinson (apparently in a Chris Rock-esque performance)
Bulkhead -
Bill Fagerbakke (Patrick from Spongebob)
Prowl -
Jeff Bennett
Ultra Magnus - also Jeff Bennett
Arcee -
Susan Blu (also the voice director, she was also Arcee in
G1)
Blackarachnia -
Cree Summer Jazz - Phil Lamarr (for those of you who were asking) Corey Burton - Shockwave (he was
G1 Shockwave too)
Tom Kenny - A Constructicon (Tom Kenny is Spongebob, among many other roles)
A garbage truck (Junkion?) - "Weird Al" Yankovic
From Seibertron:
Grimlock will be voiced by David Kaye who did a SNL Phil Hartman Frankenstien-y voice as an example. He's also doing a new guy named Lugnut.
Corey Burton, besides doing Megatron & Shockwave is doing Ratchet too.
Blurr will be reprised by John Moshita, from
G1.
They already wrapped up two seasons, 29 total episodes, with the 90 minute special (basically a 3 episode pilot movie like the original
G1 pilot).
It's traditional voice over work, where they are all together for the recording, not like anime dubs where each actor only has their lines to record.
