Has this been confirmed? I'll be able to check in a few hours. There have been cases where cross-save isn't locked by region and as far as I can see there's a universal trophy set that covers all regions and platforms of the game.
If you can check and confirm, I would really appreciate it. It's really the only thing holding me back at this point, but I'm still probably going to get them.
As far as I can tell, the trophy sets are shared between all regions. Taking a quick glance at
FFX HD's trophy list at PSNProfiles, the mix of recent people who gained trophies include Japanese, Taiwanese, Hong Kong, American and Austrian gamers. They could all technically be playing the same region's game, but I doubt that. (edit: I can confirm the list is shared between all regions)
Yes. I've checked all local retailers (I'm from Malaysia, which is under R3) and all of them tell me the same - English subs and English voices and no R3 version with Japanese voices and English subs exist.
That Play-Asia site you linked me is the only site which I've found where it's stated that the R3 versions has Japanese voices and English subs (and it's still marked as TBC). By the way, that picture of the back of the box is wrong,the product is for FFX, but the picture of the back of the box is FFX-2's Japanese box.
They seem to have switched FFX and X-2's back covers. And seeing as those back covers say the audio and subtitles are in Japanese gives me pause, even though everyone here seems to be saying audio and subtitles in English. For reference, here are Play-Asia's Chinese subtitled versions:

Doesn't show the back of the box to compare.
