Hopefully James Remar voices sideswipe, next david kaye voices hound, and last we get the leader of the wreckers ultra magnus.
Considering what happened in the season one final, I really think there will be flashbacks with Orion Pax voiced by David Kay. I have no clue about anything else.
I'm Guessing David will do some duel roles. As Orion it would be excellent. I always wished for Peter Cullen to have appeared in TFA just alone to just meet with David Kaye who i say after this will be the future face of Prime. I doubt James Remar is really in the show now. If he is cool but he would have already appeared by now. Also I wish for Ultra Magnus, Warpath, Hot Rod, Roadbuster, Leadfoot, Prowl, Ironhide and maybe someone like Jazz and a new charecter like a Autobot version of TFA Dirt Boss Decepticons: Well Shockwave, Barricade, Bonecrusher, Lugnut, Thunderblast, Oil Slick, Sideways, Jetfire, Bludgeon and a charecter based on Armada Wheeljack (Downshift maybe?).
Wheeljack will return with Sideswipe(James Remar) and a David Kaye voiced Ultra Magnus(I can dream can't I?). Shortly into the season Bulkhead will die and we'll be left with six Autobots against six Decepticons.
That too! Yes, just add in him and another female(Flareup maybe) along with the three I mentioned and that would be the perfect Autobot team.
I think they should also bring back BB's voice, I mean...what's up with that? It was a pretty good idea, but I'm sure the original voice for BB in G1 series (Dave I think his name is) is pretty sad not being able to voice the character in either to movie or TFP
