People who expect Sony or Microsoft to do more with their motion controls are probably going to be disapointed (at least early on) ...
Regardless of whether you think Sony or Microsoft has better first party developers, they are 5 years behind Nintendo with implementing motion controls in game and (as many third party efforts have shown us) this has quite a large learning curve associated with it. To make matters worse, while there are some games that this has worked well with, any game of any complexity and cost that is developed for these add-on motion control systems will most likely be designed to be played with a conventional controller; and this generally does not translate into motion controlls adding much to the gameplay experience, and (for the most part) it only makes for a different and not better experience.
When you have some studios that are completiting their third or fourth motion controlled game that is designed around the unique capabilities that motion controls provide releasing games against a studio producing their first motion controlled game that has to also be played on a conventional controller there is a massive advantage for the more experienced developer.
