If you look a little lower here, you can see what each of these pre-order gems will look like when you crack open your PS3 or XBox copy of Transformers: War for Cybertron. No, they are not specific to console as that may have sounded. They are only retailer specific. So now you get to choose which extra bot you want for your game. Well at least if you have a console that does these extras. Sorry Nintendo.
They do look rather cool, but so did the thought of Scarecrow Challenge maps in Batman: Arkham Asylum. Which should be read, they look cool, but it comes down to if they actually offer a great extra to the game or just a way to appease people who buy early. But you should be a big enough kid now to see if your fanboyism is large enough to snag one of these for being that hardcore and willing to shell out cash early.
