Nintendo of American president Reggie Fils-Aime has said that Super Smash Bros. Brawl will not be coming to Europe until the Autumn.
Speaking to 1UP, Reggie answered a question regarding why Wii Fit and Mario Kart was coming to Europe first by saying, "Yeah, but they don't get Smash Brothers until fall."
Reggie cited the reason as a production problem, claiming that Nintendo would have to open and convert new factories in order to step up disc duplication, which would no doubt prove costly and wasteful in the long run.
Sorry Europe - looks like you'll (we'll) have to be content with Mario Kart for the time being.
UPDATE: 1UP has clarified precisely what Reggie said. It seems he actually confirmed that the European release of Brawl has been pushed back past spring due to localisation issues, and did not confirm an Autumn release.
