The more reliable info leakers have said the other two leader class Kingdom figures are Galvatron and a retooled Siege Magnus with an Earth styled Cab.
Galvatron is reportably the height of Siege Magnus and has the Matrix on a chain to go around his neck. Not a triple changer this time. He also has an extra rail gun accessory that can split in two and attach to his shoulders. Some people speculate this is a nod to the Energon Megatron/Galvatron design.
Grain of salt until we see official images. But the info comes from guys who have been pretty much on the money with thier Kingdom info so far.
I have heard the same info but VERY early info yet. Sounds promising though.
