A fact sheet apparently handed out during a Nintendo event in the Netherlands shows that Kid Icarus: Uprising for the Nintendo 3DS appears to have been delayed until 2012. The game was originally scheduled to be released sometime this year according to Nintendo Europe, but this could have changed. Whether the fact sheet is legitimate is anyone’s guess, but it will be a massive blow if true.
Edit: Just spoke to the Nintendaan who confirmed it to be true.
