IMO, dvd is not dead yet.
So long as the distributors release new titles, there will always be buyers.. Although cost is now a major factor..
Gone are the days when the distributors can release new titles in multiple editions at price points of P750 and up. These days, with the barebones release, people usually wait for the prices of the new titles to go down to an acceptable level (i.e., 3 for P500 or lower)..
