these figures are supposed to be about the size of a Cybertron $20 figure (Leobreaker, Evac, Crumplezone, etc) ... so they're quite large in size.
Classics (Neo) is supposed to pickup when Cybertron wraps up. Hopefully the movie's characters will be based off of these guys. I'm almost certain that the autobots used will be in their Alternator form.
