A Blu-ray player is just a higher-definition player, and will give a more detailed picture when playing a Blu-ray DVD. It's also backward compatible, so will play today's ordinary DVD's.

All indications are that Blu-ray has won the hi-def war, so I expect that all players will eventually migrate to that, as will computer DVD drives.

This does not mean everything will be really expensive, any more than switching from CD to DVD originally meant huge expenses. The raw material cost of a Blu-ray drive should be no higher than an ordinary DVD, so eventually, the price should come down.
 
...Blu-ray disc players? I don't know the difference between the discs and also if we will have to buy Blu-ray players inventually like the switch between VCRs and DVD players.
 
there is a huge differnce between blu ray and dvd. while they may look identical in terms of the cd and such they are completely different under the hood. A regular dvd can hold 8.5gb of data on two layers. A blu ray disk can hold 50gb on 2 layers.

If you have seen hdtv then this is what you are getting with bluray! Movies in high definition. There was another format called hd dvd that was competing with blu ray but toshiba announced today that hd dvd is finished so blu ray is the way forward. I think eventually blu ray will be the norm and yes ina few years i would expect everyone to have a blu ray dvd player but seeing that almost everyone has a regular dvd player that format will not just go away over night. If you have a hd tv though i would highly recommend getting one so you can get the most out of your hd tv
