Topspin looks awesome, Roadbuster looks great although its a shame the side Mechtech ports don't work - prevents me from shoving all of the crap weapons on him to beef him up. Like everyone else I don't particularly like the lack of paint on robot mode, but the detail of the mold negates that for me. I wonder if Leadfoot will be beefed up or a regular NASCAR car?
Bumblebee looks pretty rubbish, I really don't like that gun, and how they've taken away his BB axe and arm cannon. Also the lack of paint on his feet kind of puts me off. A shame, because his vehicle mode is starting to look really good.
I'll get Ratchet if his robot is of reasonable size. Quite disappointed that it isn't Voyager though. Jolt looks thorougly awesome, but if he isn't in the film, its a miss for me purely because of the paint job
Do you even need to hear my opinion on Shockwave and Skyhammer? Wonder if the latter will be in the film.
