Avatar is 1 movie , dozens of others required DD and/or DVD added into the box to sell.
But you have no proof of this, it´s just you that makes up stuff like this without proving anything.
I on the other hand picked an exceptional good selling Blu-Ray with zero DD and it still sold like hot bread.
Blu-Ray won the war against HD-DVD and ever since it has been gaining ground on DVD as well and if they included popcorn and free coke with the Blu-Ray editions it would still be one more Blu-Ray disc in the wild, one more disc that just needs a Blu-Ray player, for example in a next gen console from Nintendo or Microsoft.
And Blu-Ray is doing exceptional well
