I've been searching for the answer for a while but I still can't find it which pissed me off a bit. So basically, I want to buy the collector's edition of Diablo 3 but I don't know which one should I get cause I can't differentiate between US and Asia version. I know both are in English and I can use US or Asia server but is there any difference? For exampe, the design box of the collector's edition or something? For your information, I'll just keep the box sealed and just keep it that way. I know some of you think this is stupid but I'm a hardcore collector and always wanting to keep my collection sealed. Anyway, I can buy a cheap diablo 3 key online if I really want to play it. Look at these two links, first link and second link. If there is no difference then why there are US and Asia sold separately? I'll regret if I have Asia version with other language such as Chinese character available in the art book or anything else in the collector's edition. I know, I won't open them but still.

I hope you guys don't hate on me for asking this question but I really need to know. Thanks!
