I think if they do a pre-order bonus this time, it would be better if the content was either on the disc itself, or you have to activate a code online in the game to get it. People who didn't pre-order last time could very easily get the the pre-order "exclusive" bonuses (except the art book, of course).
If they have to physically manufacture the pre-order bonus, I'd rather not have it. Last thing I need is another piece of plastic or a comemmorative tin sleeve. (and the last thing anyone needs is 10,000 pieces of plastic or tin sleeves sitting in a landfill).
I'd rather have something in-game.
my only regret... is that I have.. bone-itis. I'm with Coco
