I have liked Ultra Magnus since the pictures posted from SDCC! He looks great! I love the head mold and really like the colors. I definitely will be getting him. I just hope he's easier to find that Dreadwing is. I've searched all over metro Atlanta and still haven't found him.
Thundertron looks...interesting? I don't know how I feel about him. It is exciting that there might be a new faction to combat the 'bots and 'cons, but I'm still not sure. If he's in the show then I'll probably get him. If not, unless he has a pretty good in-hand video review I don't think I'll be getting him. That's one more for those of you who like him!
