I'm sure we all saw and heard the bumper. But I don't think that was Megatron talking. It sounded so, different. Was it Predaking?
Yeah it did sound different, I don't think it was Welker. But I don't think it was supposed to be Predaking or anything, just a generic voice who was supposed to sound like Welker. Or just Frank with a cold or something. Don't know why they changed it just for the finale, but maybe because the "Marathon" was over at that point?
This can only mean one thing, Predacus. A play on Galactus & Predaking. Oh, and John DiMaggio as Rathlock.
Not really. There's the comic, but the writers whenever asked about the Dinobots appearing have said "not necessarily, read the comic to understand".
For the show, it was a thread in the Prime Forums a few months ago, it was never posted in News & Rumors, that's why it wasn't front-paged. It had a source and everything, I regret not bookmarking it now that I've explained it so many times.
That thread was the one that was posted when the comic was announced. Someone overreacted and thought that meant the Dinobots were confirmed.
Only thing confirmed is that the Rage of the Dinobots comic will lead into Season 3. And the only definite part of the comic who will definitely show up, is Shockwave.
