I was saying something similar to my wife last time we were in Target. They recently added a whole aisle of Blu discs, and the located it right across from some of their DVDs. The prices on the Blus are 25-35 dollars. With some "specials" on the 35 dollar ones bringing them to the 25 dollar mark. Right across the aisle they have entire TV seasons for 20 bucks! Blu-ray will never get hold of the average user market if the prices stay $25 or more.
You add to that the fact that the difference is not that big (like it was between the VHS format and the DVD format) in comparaison with the actual DVD.
Also many release on BR just doesn't look good comparativly to their counterpart on DVD on the extra department :
