I have HDTV and still i have no plans to get blu ray. To tell you the truth i just do not see the difference.
Sure it looks slightly shinier, but not enough to justify an additional investment. And at three time the price of regular dvd's, Blu ray DVD"s are just too expensive.
I think people are have just become immune to this new pushed adoption policy by the market. I bought the dvd player because it means i did not have to fill my house with huge vhs diskettes, and the quality upgrade was rather large compared to DVD vs Blu-ray. The only reason i bought an HDTV, was not for the quality of the video output, but because this technology allowed me to get a TV about times the size of my current television which before was not really possible. But the blu-ray is a gimmick i just don't see any need to upgrade, and i think a lot of people feel the same way. When the blu-ray is offering dvd's for 5 euros' and blu-ray players for 29.95, well them maybe it might be worth the investment. But this better happen in the next couple of years, or i am afraid blu-ray may die the same death that HDTV did. To tell you the truth, i would not be so disappointed, as to me blu-ray encompasses what i feel about the ps3. Sure it is an improvement to its predecessor. But a slight tweak (as far as end user perception is concerned) will fail, if priced at several time the level of the perceived improvement.
Undoubtebly though one day, the PS3 will cost $250 and a blu-ray player will cost $39,99, and if either my wii, or my dvd player breakdown, i may consider buying one of the two (after replacing the Wii of course).
