He decided to delay the already finished DKC three months.
I remember Nintendo said they would offer a lot of great games during the 2nd half of 2013 to make up for an abysmal 1st half. DKC was supposed to be the second biggest of those games. Nintendo realized they obviously couldn't keep this promise because they wouldn't have anything for the next 5 months, so they delayed it to fill a gap during the next drought.
Guess it was their best option, but the Wii U is never going to get any momentum at this pace.
