That's pretty disappointing about the voice clips. I don't get why they like toys yelling their names all the time. "I am Optimus Prime", "Fortress Maximus" etc etc I tell ya, if I were Fortress Maximus, I'd just assume that everyone knows my name. Y'know, coz I am bloody Fortress Maximus!!
Cerebros nipple LEDS for the win though. Do the leds pulse and glow, or just flick on and off?
Final comment for now, I think it's clever the way they used the same body, but made Maximus a bit taller by increasing the size of his shoulder pieces!
