Who should foresee the design trends?

I have always received the newsletters from various interior design related organizations and magazines that published many articles about kitchen design trends and green design trends…etc. In my opinion, these articles were only trying to market and sell products rather than predicting any trend.

Kitchen companies sell contemporary Minimalist kitchen cabinets predict Minimalist design trend will be in. Furniture companies sell traditional style furniture say the traditional style trend is coming back and on the rise. The paint companies say the certain colors will be popular in the next coming season, and the paint company happens to be the only one sells those colors they claimed to be in style. Since when the design trends are predicted by design product related businesses?! Shouldn’t design professionals be the ones to predict the design trends?!
