engadgetHD:The success of DVD is the kind that consumer electronics manufactures dreamed of, and now after two years after the introduction of Blu-ray, it appears to be gaining steam even faster -- and during the worst economic crisis of our time. According to Richard Greenfield of Pali Capital, in two years there were about 1.2 million DVD players sold, whereas Blu-ray stand-alone player sales are estimated to be at 2.5 million -- no this doesn't include PS3s which are expected to be at 8 million. Of course choosing between a $129 DVD upconverter and a $199 Blu-ray player isn't that hard of a choice, but paying 30 percent more for a movie is. The news here isn't bad for Blu-ray either as it has managed to almost double its market share of the top 20 titles in the past six months. We have a feeling the members on the panel at the BDA press conference this Thursday at 7pm EST -- which we'll be covering live -- will have a few things to smile about.
