well, as far as the constructicons are concerned, I stand by my theory.
The animated constructicons that we've seen are Mixmaster, and then Constructicon Leader Scrapper. Also notice, the two they picked from the get-go, also happened to in
G1 be Devastators legs. Construction projects always start from the ground up, so I just put two and two together, and figure that mix and scrap will be the legs to a new animated devastator to counter omega supreme/dinobots. I just figure that hasbro wants them to be thought of more as individuals, and to develop the specific characters first before trying to bring in more, or bring in the combined form. Something tells me that Bruticus isn't too far off either. Consider..
Swindle = Armada, Cybertron, Movie, and now Animated, so the Trademark is current
Onslaught = Newly re-acquired thanks to the partnership with hasbro and marvel
Vortex, now this one is a little tricky. The name was kinda used preproduction for the e 2007 movie, but the name was eventually changed to Blackout.
Blackout = Armada, Energon, Movie, so the Trademark is current there too.
(Decepticon) Brawl = Movie, Again Trademark is current.
The odd man out here now is just Blast-off. I think it may have been used for a minicon somewhere along the line, but I'm not positive at all. Only name left is Bruticus, and I don't know that that's been used since RiD (3 headed mutt), with the exception of Bruticus Maximus in Energon.
That's my two cents anyhow.
