larsson, i believe he is referring to the fact that japan uses NTSC, europe alone uses PAL.
therefore konomi doesn't use PES to make US verions. The US versions of their games are closer to the japanese than the european ones.
i was in japan last august and played WE7 right when it came out. i now play WE7:I US version, and they are virtually the same, except that the us version has some newer animations, less handballs, a few transfer changes, etc...
obviously, WE7: I (jap) updated as well, but seeing as though the US version had the same release date, i dont' see why there would be much different.
by the way, since the japanese version now supports all those languages, i'm curious .... are the teams and players still in japanese characters? or when you select the language, does it convert the teams and players to roman alphabet???
thanks
