Uncharted 3 Explorer Edition - super deluxe Collector's Edition for the UK available for pre-order

[Twisted]

can anybody please clarify the distinction between "uncharted 3 dualshock japan" and "uncharted 3 dualshock asian"..as importers have big price variations amongst from what i can tell identical products...is the japan one better quality?...if i buy the "asian" dualshock?..will it work with my US ps3?..it appears as if the ones marked japan sell out fast..whereas, same item marked "asian" lingers for awhile, even though "japan" one has price markup...i'm confused?
