well, I can see what you're saying...but technically the games will probably not be region coded...at least not the BR games...since BR is rumored to share regions with NA and Asia.
We'll know sooner or later...but really...importing is so expensive! And now-a-days it's really not THAT long of a wait for titles to come over to the US.
MGS3 came out in the US first.
MGS3Subsistence only released in Japan first because of isolated technical issues and testing.
MGS2 was US first.
KH2 only came out what, a month and a half ago? And will release in a week or so.
Tekken 5 released at the same time, as will Tekken 5 DR on the PSP
I don't know, it's just not really worth the extra money for what, the extra month of play time? I'd save your money and dedicate it to something else
