Is that Palpatine, in his Chancellor clothes, being attacked by a Jedi with a blue lightsaber at the end, then going all ninja on him? At 1:27-1:29 ? (you can see part of it if your mouse hovers over 1:28) It sure looks like it. Gray hair, the reptillian black leather outfit that Palpatine wore at the begnning of ROTS.... looks like the Jedi with a Blue Lightsaber attacks him, then Palpatine goes sideways and swings around to knock the Jedi out. THAT guy with the blue lightsaber is probably the Jedi Traitor, who planted the explosion... they did say he was disillusioned with the war and thought it was meaninless... he must have discovered Palpatine's true identity!
