He's so far out of my price range he may as well be made of solid gold and come with a manservant to transform him for you, but I'm really looking forward to the youtube videos. Coming into Siege semi-cold with very limited exposure to modern Transformers I've been really impressed by the engineering in some of their transformations, but if this guy legit unfolds into his planet form, rather than having all those shell bits detach and reattach, that'll be quite a thing to watch.

Although it's got me thinking, since the whole thing is essentially a shell around the robot (barring I assume the back of his torso being the bit with the mouth mechanism?), now whenever I see him in planet mode I'm going to be imagining robot Unicron crammed into it like it's a giant pokeball.
