I would like to clarify some things.
1). I can gladly wait, and have no real intention of actually playing the Japanese versions of the games.
2). The only reason I am interested in the Japanese versions is for the Japanese WiFi events (I am a little bit of a completionist) and think that it is silly that each cartridge can only have three wonder cards, so I use a flash card to play just enough of the game to download events, then create backups of the saves with/for each event).
3). Considering my point number two, a simply menu translation is all I care for.
4). I know the game is not out, thanks. I simply assumed (which I will try not to do again) that B&W will be like previous generations (at least in this aspect) and there fore also assumed (again, won't do that anymore) that somebody else thought the same thing, and could let me know if it has worked on previous generations. I only have the pure Japanese versions of D/P/Pt/HG/SS, along with the English cartridges, wombats not tried this myself (I run a Mac and so most patches can't be executed on my machine, so I haven't tried).
Hope all that clarifies my questions and why I asked, not that that really mattered.
