in the new cartoon, based on the events in prime: We shall probably have several factors involved: "New characters" could mean WFC/FOC characters Arachnid is a Vampire Insecticon queen! In Preds. Rising, you could see other protoforms in Shockwave's lab. this could mean that other Predacons will be in the show. Abominus, maybe? Optimus prime will come back. as we all saw in G1( and ROTF), Optimus NEVER stays dead for long. he will come back as bumblebees mentor. Drift and Windblade will appear. How's that for new? Megatron has gone rogue. Starscream will replace him. He just has to live his beat-down How's that, eh?
