Bluray will not take off, it's as simple as that.
There are too many people with DVDs, and 90% of them will not want to buy a 1000$ unit for something they already have.
Unless DVDs cese to be produced, there is no point in Bluray.
http://en.wikipedia.org/wiki/Holographic_Versatile_Disc HVD is something worth upgrading for however. This thing will come out in about 5 years, and maybe then DVDs are ready to go.
DVDs arnt going anywhere, there is no point to buy Bluray.
The fact is, VHSs are still being produced for new movies, DVDs will still be made for years and years to come, Bluray is simply just the rich mans toy. Why would the normal person buy something so expensive when they could go get the same exact thing for a cheaper price?
