Tekken 6 PSP (Where to buy?)

Could somebody tell me why there is a ~$5 price difference between these two -

The only thing i could figure out is that one's for "asia" and the other marked for "US".. but PSP games aren't region coded, so whats the go?

Would it be better to buy from playasia or EBGames? I've preordered from EB for $60 but i can cancel and get my money back, which I will if it's cheaper from playasia.


edit: Just realised, the US one could be english and the asian one in chinese -.-

chinese one will probably be chinese but the price difference is because of different production locations.

Stuff it, I'ma jst go EB this Thursday. Cbb waiting!
