I don't think its that confusing really. To me it seems like a lot of people just start spouting off whatever they think Superbot means when they say something, without actually thinking about it. People assuming bonus costumes were only for the pre-order, instead of everyone having a bonus costume, and then the 10 who get the pre-order ones having 2 costumes.
Omar - "what are you guys doing? Why did you get rid of crash!"
Game devs - "we wanted to put in evil Cole so we had to get rid of everyone else the fans wanted"
Omar- "Oh nice, good idea. I didn't think of that"
I talked to a rep today, and they said that unless the company releases an edition specific to a region, a preorder bonus is international.
Example: If this game had a special edition specific to Europe, and the cards were a preorder bonus for that specific edition, then only GameStops that were retailing that edition would be getting that specific bonus.
