Powder or park

Currently i use a pair of all mountain skis that are good in the park but wide enough to handle a little extra snow. I can get skis for christmas....but I don't know what to get. the skis that I'm riding now ar a year and a half old and one of the inside edges is coming off.. I don't know wether to get new park skis. or buy powder skis of the days its dumping. I was thinking maybe buy powder skis and use my current ones for the park.... or vice versa.....
