Does anyone still have the link from NeoGAF where someone made an indepth analysis on how infrequent NoA localizes games nowadays in comparison to their past? I'm sorry but I just can't believe most of these reasons are valid when Nintendo had no problem localizing Odama 2 1/2 year ago when it was obvious that game wouldn't sell a lick in the US.
Edit: One more thing. This game was unveiled at E3, a convention for american gamers. If Nintendo was going to go out to showcase the title here in America, the least they can do is release it here.
