Okay, so we've seen that we'll be getting 8 sets of parts for each class in the game, that means 32 different sets of parts, which pretty much breaks down to 32 characters we can mix and match with. So, lets make a list Infiltrator -Bumblebee -Cliffjumper -Jazz -Sideswipe -Wheeljack? -Breakdown -Deadend -Swindle? Destroyer -Optimus Prime -Ratchet -Ironhide -Onslaught -Soundwave Titan -Warpath -Scattorshot -Perceptor -Megatron -Brawl -Demolishor Scientist -Jetfire -Air raid -Silverbolt -Starscream -Shockwave -Vortex -Blast Off? So there's still a few missing, might have missed some but it's still interesting to think what other characters haven't been revealed yet.
