If i remember correctly, the Japanese SSBM when it was released could change language into english, in the options...thats what my friend and me did in Taiwan. (taiwan=japanese GC japanese game, so japanese SSBM) so yea, jp-brawl maybe will have english option too...
but i dont know if the english option was there since it was first released or if it was added later i'm pretty sure there was a language option though...
anyway i live in France, but i bought a wii in japan (summer vacation), and since the tv i have in france is a very recent expensive plasma SONY TV, I can play jp-wii on it YAAAAY...and i know an import shop where i live so ill have brawl whenever it comes out in Japan...maybe i wont be there though..lol
although guys, its just 11 days (IF, it comes out the 22th-nov in japan), you can wait..prolly...
as for european smashers...COME TO MY HOUSE IN LYON!!! jk its too small....
yea, as u can see i travel a lot...right now im in california lol but who cares...
