Preorder your Demon model

I'll juss wait till its out on the shelves. I HATE "pre-ordering" as when it does "finally" come in the mail I get the hairy eye-ball from the wife "And WHERE did you get the money for that" is the next following thing out of her mouth.......AND not lye about it, asking her "want the truth, or should I lye? Then the **** really hits the fan, usually blows towards me! SO...... I'll get mine when they're seen on shelves in stores!

Anyone know what the power plant is gonna be in the model from factory? (Not that it matter to me much but is nice to know!)
