Previously expected as an Xbox One launch title, Kinect Sports Rivals has been pushed back.
Polygon reports the Rare title is now expected in northern spring 2014.
It had been down for a holiday 2013 release, in the Xbox One's launch window; the new console releases in November.
Rare will use the extra time for necessary polishing, but it will still be on show at PAX prime and gamescom next month.
Kinect Sports Rivals is expected to be soemthing of a showcase for the new version of Kinect, which is described as far more accurate than the Xbox 360's. It will have climbing, wake racing, soccer, target shooting, bowling and tennis.
