I've been reading that the 2012 release is similar/the same as the 2-pack with movie Prime, in which case, colour-wise, I'm happy. I'm not terribly worried as to how accurate the colours are (particularly since one of my favourites is the cartoon movie-coloured Galvatron) as long as they're correct in a broad sense.
And the cab isn't pink.
Ideally, I'd rather have tampos than stickers for Prime's shoulders too.
