With the internet people's buying habbits have changed...

People buy instruments when they are newly released. If an instrument is 2 years old, they barely make any sales, as people will have started wayting amd saving their money for a new upcomming release...

People in this age, know much much better what to expect from companies like Korg amd Yamaha.. and only a very few lay out a huge amount of money for a 3 year old instrument.
