Nathan Fillion As Ultra Magnus?

Do you guys think Nathan Fillion (Castle, Firefly) is voicing the Wrecker Commander Ultra Magnus?
Here's why I think this might be...
1. In the three part season 2 opener, Optimus/Orion Pax was working on the files in the Decepticon computers When he searched for any info on Optimus Prime, an image of Magnus was on the screen instead.
2. There's a Cyberverse figure of him (Out now) and a Voyager (Coming soon) that seems to be a brand new mold.
3. In the episode "Loose Cannons" Wheeljack mentioned Wreckers that were now offline (Pyro, Seaspray, Roadbuster, Impactor, Rotorstorm) but did not mention the group's mighty leader.
4. I think Ultra Magnus would add alot to the already impressive season. Maybe he shows up to collect his teammates or something. Maybe he might show up in a flashback for Bulkhead so that we can learn more about his days as a Wrecker.
