Game was never delayed, rather is being released in the "launch window."
After IGN reported that Elebits was delayed until December, we contacted a Konami rep to get the details. He told us that the game has always been planned for the "launch window" and those plans have not changed - terming this as a delay was incorrect, and IGN has since updated their news story. The Konami rep also stressed to us that this does not contradict the inclusion of Elebits in thelist of launch games given by Nintendo in a press release. Rather, as the press release indicates, this is a list of "launch window" games, meaning those without firm release dates may be released next to Elebits in mid-December, later than expected.
