Not really a hole in one.
Mario Golf: World Tour has been delayed until 2014.
The delay was revealed in a chart during Nintendo's E3 Analyst Briefing. The game was originally scheduled for this year but has been pushed back for unspecified reasons.
In the same briefing, it was noted that internal development teams have reached the point where first party titles can be released "without too many intervals." As such, Nintendo expects to release many 3DS titles in 2014, including many unannounced projects along with known 3DS titles like Mario Golf: World Tour.
