First up, give it up for the Protectobots! The ranks of the Protectobots include their leader, Hot Spot, and his subordinates Blades (retool and redeco of the existing Alpha Bravo mold), First Aid (who is rather jeep-ish), Rook (who transforms into a APC-like SWAT vehicle), Streetwise (sporty-looking police car), and Groove, who is now confirmed to be Legends-sized and also pulls double duty as forming armor to Defensor ala Generations: Combiner Wars Menasor.
Fans of the IDW-verse rejoice as they gaze upon Ultra Magnus... who not only rocks an IDW-themed look, but also includes his actual self, Minimus Ambus, who is capable of fitting inside the big UM and transforming into a Cybertronian vehicle. Also worth noting, as demonstrated in the last image, his shoulder-mounted rockets and rifles are capable of combining into a giant hammer, made iconic by the Animated version of the character!
Keep your optics tuned to us here at Seibertron.com: we expect to get official images of all of these figures sometime tonight!
***UPDATE***
We also have new images of Voyager Cyclonus, who forms the torso of the gestalt called "Galvatronus" whose head is based on (you guessed it) Galvatron (no images yet... stay tuned!), and Legends Warpath and Viper, the latter of which is an homage to a GI Joe vehicle, the Cobra-affiliated Rattler.
its a great time to be a TF fan 
Which brings the pairing list to this:
