I'm not usually one to speculate much about something so miniscule, but hey, why not bring it up.
If you go to the Pre-Order section of the website (http://www.playstationallstars.com/Pre-Order) you can see on the right (where the characters are listed) that there is a list of characters of which you recieve costumes for.
What's a little odd is that Kratos, Parappa, Sly, Fat Princess, Radec, Sweet Tooth, Toro, Heihachi, Big Daddy and Drake are all listed twice.
Could this mean that these characters have 2 costumes? Or is this just a small mistake on Superbot's part and nothing of any importance?
Personally, I think it's nothing. But what are you guys' thoughts?
